"What effectively the police did was come in and stop 15 people eating burgers," Poole said.
The event was shuttered under section 63 of the Criminal Justice and Public Order Act 1994, which grants police powers to remove persons attending or preparing for a "rave" (defined as playing amplified music "wholly or predominantly characterised by the emission of a succession of repetitive beats," during the night).
Don't these bozos have real crimes to investigate?
And as a side note, I used to do the rave scene in Los Angeles, and the definition in section 63 of the Criminal Justice and Public Order Act 1994
is, to but it mildly, woefully incomplete! :)
