How To Break The Kettle: An Illustrated Scientific Guide
Mrs Nov 30th | 28.11.2010 00:34 | Policing | Repression | Social Struggles | Technology
Wedges are really a kind of inclined plane. A wedge is two inclined planes back to back against each other. The mechanical advantage you get from a wedge depends on how thick it is. A thick short wedge will split things apart faster, but you'll have to use more force. A thin long wedge will be easier to drive in, but it will take longer to split something. Today we have many different uses for wedges.
Sometimes life present us with a problem that we cannot solve without the use of a classic piece of scientific thinking. In today's puzzle, we are trapped in a kettle, surrounded by police officers and we want to get out of it. We have tried shouting en masse 'let us go!' but this has not worked for us. Next we need to do some collective thinking and put a new plan in effect.
The first thing we should do is look for which police line seems the weakest and with the best chance of escape should we break the line. This may be a line of normal cops without riot gear and usually only one officer deep. Here how the work might proceed.
In Fig 1 we see the crowd attempt to break the police line by using opposing force. This can sometimes work but usually the police can brace themselves and hold each other and thus hold the line. In this way, the strength of the crowds' force is lessened and absorbed by the police line.
In Fig 2 we the crowd attempt to get technical and use a banner or metal barrier to push the police. The same dynamic occurs again and the crowds' force is lessened and absorbed by the police line.
In Fig 3, the crowd has decided to form a wedge shape to drive a gap in the police line and follow though, the thickness of the crowd opening more and more of the police line up.
In Fig 4, the crowd knows that the police line weak points are at the extreme ends of the line as the final policeperson has no brace or support. The crowd attempts two pushes on the line at the weak points.

Will be posting a pictoral step by step guide on the site later...but its not rocket science...
Step 1...sheet of plywood or similar (dont use the garden gate-you'll still have to transport it)
Step 2 ...bit of battening and a handle type thing on the back (could reappropriate one from a public loo door..?)
Step 3 ...Decorate the front with a suitable slogan / poster of choice
Step 4 ...Finish your ensemble by wearing a cycling / skateboard helmet
.... Bingo - ready made sheild and headgear strong enough to take a battering from the truncheons of dibblewhilst exiting the kettle!
Check the photos from an earlier post of this in action by our Italian comrades

The Simple physics of kettles
28.11.2010 16:12
I do so enjoy your night classes. You get so much out of them. I remember your Tai Chi classes. It was the last time you described me as a "patronising bastard". Thereafter you just beat the dobby oil out of me.
My point is: yes creating a wedge at the weak points is an excellent idea. But remember: if you have a strong point at the centre and two weak points either side then the strong point at the centre will surge forwards. You need a tactic for when that happens. Do you create a protestor weak point at the central police strong point, on purpose, for the police to surge through. It might allow those at the police weak points to move forward but then cut the crowd in two. Perhaps a follow on tactic of a circle mosh pit might work. Certainly you might want to look at the computer game version first: http://www.pyweek.org/e/Wibble/
Now get thee back to thy knitting - or did you take up that course in economics instead.

Banners should from a wedge
28.11.2010 16:13
Banners made from wood can be used to form a wedge
These crash barriers can also be used to form a wedge
More useful is if we use banners to break out that are ones that are hinged in the middle, or tied with good rope. Or use two metal barriers for crowd control that are still bracketed together. Equal force is usually not enough to break through. The point is to split the line with a wedge.
If you look at the two pics: The two banners are made from strong wood and can be used as a wedge to force the line. The other pic has many crash barriers to also form a wedge with lots of folks behind. Both of these ways through should be held high enough to stop cops hitting those behind with batons. But you also need a lot of people behind to stop the cops just shutting the line again. Once it's been broken, the more who come through, the harder it is for the cops to regroup in a new line.

Circle pit?
29.11.2010 00:01
I was thinking last week how a 'circle pit' might be an effective way of breaking out of a kettle given enough people, and enough thought about how to avoid weak points in the circle.
However, given that most so called 'punks' at shows don't know what a circle pit is nowadays, it could be difficult to gather enough people and momentum, not to mention the problems of people falling down (the police can knock us down and make things dangerous enough without us doing it too), and how terrifying it can be for anyone who is unaccustomed to a circle pit or the first-timers in a kettle.

Easy crowd coordination: Hokey Cokey
02.12.2010 20:21
You put your left left in,
your left leg out,
in out in out
shake it all about
You do the hokey cokey and you turn around *not necessary if the front line of people have their arms linked*
That's what it's all about...
OOOOOHHH THE HOKEY COKEY
OOOOOHHH THE HOKEY COKEY
etc. etc.
This has worked for crowds at football matches trying to get passed police lines, and I think it's good as you get three surges at the end. It's also easy to start (with a loud voice) with no instruction to people beforehand -most people will cotton on quickly to what's about to happen. And the police will know it's coming but can do nothing about it...

while this all sounds very pesimistic if you are going to make a reinforced banner:
- reinforce the structure somehow, possibly make a insertable cross beem to hold the shape.
- make it hard
- make it big to provide protection to all parts of your body
- put lots of handles on it as many as possible.
or
- protect your own body and encourage your friends to
- be dirusptive bounce about poke police
- if you do break through the line dont just run off, get to a point where your safe from being re -kettled then if possible go back to the back of the cops stand behind them push them make them feel like there surrounded.
- the book block worked very well last time.
our strength comes from our autonomy and ability to react to the situation thinking on our feet.trying to beat them at their own game of overwhelming force is difficullt because you cant get all the equipment on the tube! Although it would be nice to see a sexy reinforced banner work.
In this video you can see the banner in action from 13.07 and 14.51 you can hear the police discuss smash edo briefly.

We're here for the long stay, not just a day.
Pro action; Tent deployments allow large areas to be taken very quickly.
They will stop police charges, especially mounted ones as they will not be able to ascertain what tents are occupied and what ones are not (Health & Safety).
Each tent will have to be dealt with by the police individually, 1,000 tents + would create a logistical nightmare.
Your basic 1 person tent takes up an area 3 x 4.
people's assembly
fuckin' tents! Noooooo

That's just fucking dangerous nonsense. It was even obvious before climate camp in the city. The police charge over tents, they smash them up, they go round them, they push us into them as they are a fucking liability and obstruction.
Let's let go of this damn obsession with camping!
Read the EF! guide above for hints about barricades/obstructions. Basically a forest of tents/a solid barricade is bollocks for us, however the careful placing of objects that stops police lines but not us works.
been there...
Weak points, metaphorically
26.03.2016 17:59
If you could identify someone with such a "weakness" in direct confrontation, they probably are the easiest place to get through. How would you recognize them? I suppose the look on their face, or their response if you approach them in a way that could be considered gentle - through your own looks or actions - of course not subservient, but treating them as an individual rather than part of a mass.
I'm interested in comments from people who have actually tried this. I'm speculating.
