They are a part of the same police force. I’m not saying they’re good people. I’m saying this role is not one doing harm, and is actually useful until we get our shooting issue under control. You’ll see the same snipers at sporting events and anywhere else with a large gathering. They’re obviously not there for the protesters, but in case someone decides to do something to start killing others.
No Idea. My university did a yearly celebration as well and we for sure had snipers and guys with rifles walking around. If you know where to look, they’re at most large events. I can’t tell you about this location specifically, but it’s common.
