Theres nothing to be done unless we can control crossings at our border. The options there are physical barriers, violence (ie shoot all crossers), or get Mexico to prevent them from reaching it in the first place (which would probably be via violence as well). As I imagine most would, Id much prefer a barrier to shooting people. We need to stop turning them loose in the US as well, as that incentivises more crossings. If we cant house them, they should be bussed a fair way back into Mexico.
