I am only a contractor who flies for the police. However, since when can't you criticise them?? Just because I disagree with comments in this case doesn't mean I won't have a go at them when it is deserved. There are some people on Pprune who will have a go whenever they can, when they are corrected, they claim that the police will never take criticism.
I stand by my statement..... If you pay for security at an international airport, you expect this NOT to happen. Fairoaks is a different story, the security SHOULD have been better but the system was to blame, not the individual crew. You are not expecting or fully equipped to deal with weapon carrying criminals. If they need to sit with body armour/taser/CS all at the ready then lets give them the kit or up the local manning levels to support the requirement. I would not want to face petrol bombs and axes armed with a set of Flight reference Cards and a chinagraph!! Our crew leaves the site, short term, to carry out admin tasks/fuel management, leaving me manning the pumps. I do not get paid to face weapons. So please cut some slack for the individual crews involved. Criticise the management by all means, but remember they are under intense financial pressure.
PS. You will get my full support for having a go when real mistakes are made.
