Depending on the state ( in the US) security guards can have all the same powers as real cops. Literal rent a pig. Also depending on the state, security guards are little more tham unglorified receptionists. The exact same job responsibilities, plus being cpr cert'd, for half or less the pay.
Which reminds, y'all be nice to receptionists. That job sucks. be dicks to security if you want to, most of them are only there for 3 months, and the ones who stay longer are probably bootlickers, so, y'know, you do you.
He’s talking about the USA, so the guard could shoot your neighbour and be suspended with pay. If he wants to be extra cautious, he could yell stop resisting after shooting him.
