They knew I had a vest, and my demands were stated clearly for them to put their hands up or be killed. They clearly knew based on where i was position that if they did not put their hands up, they and the shed would blow up. You can see in both POV's a cop inside the small shed attatched to the shed which I assumed was in my radius, Edge was in they yard close to the radius. Technically speaking I could have detonated as soon as I dropped from the orca, however I had the decency to sit there and re engage (during an active engagement) to see if the cops would comply, they knew I had a vest and the patrol officer was surely in the radius of detonation. Clearly after the patrol officer bordering the shed refused to comply, I detonated. If that officer had complied, I would have had no reason to detonate, hence why I waited to detonate.
To reiterate my point: We were already engaged when I dropped, I re-engaged and waited on the roof. A patrol officer, close enough to have a large chance of dying, did not comply. He was met with appropriate action. If my intent was to just blow up the shed, why didnt I just detonate when as soon as I dropped?
