What is going on?!?!?
This sounds like a gang thing. Imagine the cred someone would get for shooting an officer in the station.
Possibly, but I think this murder has a socio-political angle.
We have been lucky here in the US in that deliberate and unprovoked attacks on law enforcement by criminal gangs are very rare. I can only think of a few examples including a biker gang murdering a judge and a white prison gang murdering a prison administrator. This could well be because such murders bring far more police attention to the criminals and impacts tjheir other activities.
In the meantime, there have been more unprovoked attacks on police in recent years by terrorists (muslim extremists, as well as by locally produced left and right wing political extremists). As the death of police is the sole goal of terrorists, they dont care about the intense and focused police attention.
