"In possession of long barrel weapon under 18 = felony
In possession of short barrel weapon under 21 = felony
Scratched / unserialized weapon = felony
Drive by shooting = felony
Drugs and any weapon = felony
Felony reckless endangerment = felony
Evading and eluding / high speed chase = felony
Assault on a police officer = felony?"

Yeah, but what is important is that all of those charges are known after the fact as a result of a police pursuit, not at the time the pursuit was initiated, all that was known at the time of the pursuit was unlawful discharge of a firearm in a parking lot. Sounds bad and all but not really that big of deal and definitely not worth a cop giving his life up for and certainly not worth putting the kids they were chasing and the public at risk of loss of life and destruction of property.
at least that's my opinion.

I ain't down on the cops, they just are doing what they do but it isn't worth chasing cars if its not a life or death situation.
