You're correct and this would work, however this will degenerate into racist attacks on any minority, and will ultimately and near immediately descend into attacks on legal immigrants. Legal immigrants already deal with being shunned by law enforcement, and their tolerance to organized crime is because it's often your only recourse when shit hits the fan. The retaliation for a wrong target won't be a call to the cops. It will be your house being burned to the ground, it costs about $5,000 (or a favor, which is just some "courier" work) and the chances anyone will be caught is next to zero. This is one to leave to the police and ICE, or it will be a race war and you're not more capable than Somali child soldiers.
