What is going on in Dundalk?

Twenty to thirty chemicAL suited individuals have been observed here in the last 30 or 40 minutes positioning themselves throughout the centre of the town from the square right up Park Street. They are replying to querys about their presence by telling people to go about their business. This is a new one on us here in the town. Even the local Gardai seem to be clueless as to what is going on. They are however pointedly not interfering with the individuals in question. What is going on? What are these people up to? There is nothing on the news to suggest anything is amiss.
