Since posting that, I thought about it myself. Over here in Germany, we have similar laws, but it’s specifically securities, not police. The massive difference being that those securities don’t have guns.
And yeah, that was basically my thinking. Why would you send people with guns to such an event? It just causes everyone to feel uneasy. And unarmed securities can break apart brawls much more aggressively.
…but yeah, I forgot that everyone and their mother has a gun in the US. Unarmed securities would be on a suicide mission. So, yeah, I do understand now, why police is present…
