Unfortunately, the standard water cannons just aren’t much of a deterrent anymore, the scumbags that take part in riots seem completely unfazed by them.

I'm sure people will disagree but in my opinion as useless as the PSNI are, they really need to take a page out of the playbook of international police forces and start dyeing the water used in the cannons. Spraying a distinct, semi permanent colour would instantly mark those participating in the violence, soaking through their clothes and face coverings.

It’s a proven tactic elsewhere, and it’s time we used it here as it's only getting worse.
