To borrow a turn of phrase from Jeff Foxworthy:
"If you hate guns, but are willing to sic a SWAT team on someone who pissed you off, you just might be a liberal."
Michigan law requires registration of all handguns, and payment of a fee, under the guise of a "safety inspection."
Of which is sounds like Angel was in the process of complying with when his ex-wife sicced the cops on him...
