There have been several isolated clashes.Many of the protesters were angry over Trump's decision to deploy National Guard troops to the city."I would love to say that it would make things better, but based off of the actions of the people inside without supervision, I have a feeling that this camp will be targeted very heavily," Ritto said. "And all we can do is prepare and protect each other."A helicopter was also observed flying over the ICE facility on Tuesday night.
