During a recent visit to Chester I was struck by their security guards, not literally, but I couldn't help noticing how visible security is at Chester and how seemingly over the top it is. The security staff are dressed in police type uniforms with stab-proof vests and radios, they even drive cars with police-like liveries.
Whilst I'm sure most zoos have some form of security, I can't say I've ever noticed it, I vaguely think I may have seen a security person at London Zoo. Does Chester have a particular problem with unruly guests or is it all just a bit OTT?
