Sharing guns on the border?
Check it out:

Guns are in such short supply at the Border Patrol that one agent told 400 agents share just 100 rifles at his station.

The lack of weapons is more than just a nuisance, according to law enforcement authorities, who say each agent should be able to calibrate his or her gun to individual preferences, a process they call “zeroing.”

“We are left to check out rifles that were unzeroed to us,” a border patrol agent told “This practice needs to be outlawed, as it could cost someone their life.”
