The last time I was in A&E there was a loudly drunk man sitting to one side telling the security staff that they were failed Policemen, and were just as corrupt as the Police. He continued this rant for about half an hour and refused all requests to STFU, so security went to call the 'real' Police, Just as they arrived the drunk did a runner out of A&E and down the corridor towards the X-Ray department. The Police asked where he had gone and everybody in the reception, about 40 people, all pointed out the direction he had run.
About 2 minutes later he was frogmarched out, this time ranting directly to the Police about how corrupt the force is.
