In our apartment building we’re told not to let anyone in unless we know them. “DON’T RECOGNIZE THEM. DON’T LET THEM IN” People take the signs down. If they live there they should have a key. If they’re guests they need to buzz the apartment and be let in that way. I wouldn’t get on an elevator with four guys who entered the apartment by piggy back mode, or who tried to force their way in by any other means. The first article said it was a hotel, now it’s an apartment building. Follow the rules is the best policy. He apologized for the gun. They could have had guns too. In an apartment building there is no designated person with authority to keep people without keys or who don’t want to use the buzzer system. It’s the job of the tenants. Some do it. Some don’t. There is a fear factor operating here when the rules aren’t followed, if indeed there were any.
