So they are comparing the ones in ICE custody. Secure communities is dead, so ICE primarily holds those busted for crimes. You get arrested, go to a trial, get convicted, and before your release ICE places a detainer on you, and you get handed from jail to ICE jail before your removal proceedings start.

Maybe he should compare them to the amount of the domestic felons, or maybe to Detroit, one of few places in US where carrying an AR-15 openly isn't exercising your 2nd amendment rights, but just common sense.
