You’re right about overreach. Still, the reason he was detained is not the mystery the article tried to portray it as.
Also, DUI is a violent crime. It should be grounds for immediate deportation. I don’t understand why Mothers Against Drunk Driving isn’t speaking out on this.
I have mixed feelings about deportation for first offense DUI. This even though people I know & worked with have been killed by a drunk driver. (Great guys & excellent musicians - the one could play the wah-wah guitar solo from “Salisbury” as well as or maybe even better than Mick Box. They got t-boned, going home one night, by a drunk driver who sped through a stop sign at a country road intersection. I don’t recall the exact blood alcohol level, just that I was surprised that the killer had made it 100 ft. ft. down the road without going into a ditch first. He survived, of course.)
But still, blood alcohol limits are so low in some states now... I’d say heavy fine, maybe 200 hours of related community work, and a stern warning that if repeated, the offender does not get a 2nd chance. Also, if anyone got hurt on 1st offense, or there was a serious accident, out you go. OTOH, if the DUI was a 1st time stop for such, and is not repeated, after 5 years or so, it is not held against you in deportation considerations. This especially if the evidence indicates the offender has corrected his / her course and is a valuable resident of the US.
As for the article, what I came away with was that ICE is justified in taking a hard look at the guy, but he should not be “automatically” deported, and there should be some arrangement (ankle monitor?) where he can continue to work, until his case is determined.
That said, maybe there are additional factors we do not know.
