 He'll serve his 30 months, get deported again and come back in illegally again.  The crimes he may commit here before he is caught again are pure  speculation, of course.  Remember the San Francisco 'sanctuary city' murderer had been deported five (5) times before he 'found' that stolen BLM gun and 'accidentally' killed the woman on the docks.

As Trump says, "Some of them are nice people,"  Maybe this one will quit fondling 9 year olds next time he comes back.

That's why we need at least a fence, not a revolving door operated by cartels who use the illegals as mules to bring in heroin, marijuana and meth.  And when the cartels are in bed with the Federales, as well as  the local border governments, any 'agreement' between the two countries is useless.
