SAN FRANCISCO — A protester who was initially charged with misdemeanor assault has been sentenced to probation for a less serious offense, ending a federal prosecution that only started four months ago, court records show.

On Dec. 8, Angelica Guerrero, 35, pleaded guilty to misdemeanor “depredation” of an ICE van’s tire — a fancy legal term for slashing it with a knife. The same day, a federal judge sentenced Guerrero to probation, according to a minute order of the hearing.

The charge stemmed from an Aug. 20 protest, when Guerrero slashed the tire of an unmarked Chevrolet van being used in an ongoing “enforcement and removal” operation by the Department of Homeland Security on the 100 block of Montgomery Street, according to prosecutors. The complaint alleges that Guerrero “made repeated threats” against one of the officers, including stating, “I’m going to (expletive) you up” and “I’m going after your family,” as well as threatening to stab the officer.

Guerrero was released within 48 hours but complained of “barbaric” conditions inside Santa Rita Jail, during an interview with ABC7.
