Does this not already exist - in the form of first degree murder or first degree assault where LE are the victims? Were EMS not previously included? Imo, at first sight, this seems to be a reaction to the latest shootings of LE in various cities - where the perp claims retaliation for LE killing minorities that were unarmed.
LE needed another law or higher protection? Maybe first responders needed to be included? Like I said, the law seems to already exist. Is this addressing the core problem? Might be, but not seeing that at the moment. Will this fix all the problems LE has right now with the public? Will charging someone under this law bring a higher sentence? What is higher than the death penalty - which seems to be part and parcel of killing a law enforcement officer?
Fwiw, not seeing how this will prevent targeting LE in the future. Everyone knows the penalties imo.
