Claiming that attacks against agents have increased to terrifying levels, the U.S. Border Patrol plans to arm its agents with paintball guns and shoot the got-aways who perpetrate the attacks.

Wikipedia reference to paintball guns (markers) used by law enforcement:

Paintball markers have been used by law enforcement as antiriot weapons, in two modes:

• Loaded with pepper-spray projectiles: see Riot gun#Pepper Ball rounds.
• Loaded with paint projectiles to try to mark particular rioters so that police can easily identify and arrest them later.
