Why shouldn’t they have been there? By the logic of the other poster, having the national guard with rifles lined up would have protected the protesters from an active shooter. Wouldn’t everyone be so angry at the police if they didn’t stop the active shooter with the national guardsmen?
Is there something special about being a sniper that makes you not a cop? That makes you not part of the same system, the same trainings, the same culture, the same lunch room, that leads regular officers and riot cops to brutalize protesters, especially those on the left? Is there some requirement that to be a sniper you have to be extra nice to leftist causes?
The fact is that absent some specific threat the department received, or some extra-special high value target/event (Superbowl, presidential address, etc) the use of snipers to “protect” the protesters is a farse. We should both know that if anything the snipers are there to “protect the university and its property” much more than the protesters because that’s what the rest of the cops are there for.
