The mechanism to do it properly is the feds working with local and state officials where there's a full breadth of accountability and judicial coverage. Some states and cities have explicitly rejected doing this, some opting to purposefully make it harder. Trump instead of being diplomatic and trying to work with them has aggressively sent goons in to do flashy operations and pushed federal enforcement to the limits of the law.
ICE and border patrol wasn't really designed either legally or in training for these sorts of large operations, so it's created lots of dangerous situations like how to do crowd control broadly under laws like "interfering with a federal investigation", while commanders are pushing them hard for results.
