Trouble at london free parties has gone from bad to worse.
Not so much a few fights.
But more muggins, knifepoint thefts, a few people getting slashed now and again.
Essentially down to drugs, the sale of them, and the fact that many people get a bit too trashed and make victims of themselves.
Although they could be policed a bit better.
In this case it`s not so much trouble makers, as predators.
