Discharging a firearm is Discharging a firearm, Unless they were in fear for their life. Some DA wanting to make a name for them self might press charges.
. Not sure how it works done your area. Up here, UNLESS i'm in fear for my life, not only an i not discharging a firearm. I'm not chasing anyone anywhere with a gun in my hand.

ESPECIALLY WITH LE'S IN PURSUIT.
