They're not arguing that they're better than police, they're saying that police have protections other people don't, and those protections are the only reason they feel comfortable kicking doors down. You're very, very unlikely to find some private security guy willing to kick a door down for some trading cards, because pretty much the first time they're wrong about it they're going to jail. You don't get qualified immunity as private security.

And that's an awfully long paragraph when "no" would have sufficed just fine.
