A second deadly ICE shooting in a week has set off protests across Maine and become a major political problem for Republicans.

• ICE agents shot a 26-year-old Colombian man in the head during a car stop near Biddeford; he was applying for asylum and had a work permit.
• He was not even the person ICE was looking for, and the agency admitted its officer fired out of "fear for public safety," not fear for his own life — a claim unlikely to hold up in court.
• ICE took 12 hours to respond and offered no real defense, effectively admitting the shooting was unjustified, a sharp break from earlier cases where they blamed protesters.
• Neither this shooting nor a similar one in Houston last week had body-camera footage, fueling claims agents avoid accountability.
• The killing lands as ICE pushes an aggressive new quota of 2,000 arrests a day after getting $70 billion in fresh funding, a bill Susan Collins cast a deciding vote for.

Outlook: Democrats running for Maine's Senate seat are seizing on the shooting, and it could seriously threaten Collins and Republican control of the Senate.
