Dear Tom, the security guards MURDERED Jiansheng Chen. Your numerous questions about what training security guards should receive and how they should be treated doesn’t address the fact that they killed a 60 year-old man. Being a former cop I expect you to side with the security guards. Are you seriously proposing that more training would have resulted in a different outcome? As you’re well aware many off-duty cops work as security guards, would an off-duty cop be justified in murdering a motorist simply because he was playing Pokémon Go? Lets address the real issues, campus security across the country have been turned into police, public transportation security have been turned into cops and off-duty cops work as security guards, bouncers etc. How long will it be before security guards are given police powers, a year or two at most?
