The difference is the shooter in the tower is actively shooting at police or the public. Your terrorist in Yemen's execution was ordered regardless of what activity he may have been engaged in at the time of his execution.<quoted text>
A shooter in a clock tower is taken out by SWAT. Why wasn't the shoter arrested & brought to trial?
A US Citizen sits in Yemen sending bombers to kill Americans. Why isn't he captured & brought to trial.
What is the difference?
If we knew where a terrorist camp was that had several leaders including a US citizen terrorist leader & send in helicopters or a scud, would that be OK with you?
I don't get it.
What's the difference if this American Terrorist charged a US installation as part of an attack or if he hid in the mountains with a sniper rifle or commanding others to attack us.
The objective of the police is to subdue and arrest the shooter and protect the public, sometimes there's no other way other than to kill him. Nobody ordered them to execute him before they left the station.
