Considering how public they have been that they would not accept a vigil like this in previous days, I think it's clear that they'd stand their ground.The police make choices.

Which decision do you think would be the wisest one in this situation for all parties?
I don't personally think it's the best way to go in the current atmosphere but it is almost expected
