At 36:10 Michael, Alex, and Kyle run out of the prison a mere eight seconds before it explodes. The building is leveled in five seconds. A detonation strong enough to level a concrete and steel structure this quickly would have sent out a shock wave that would kill or maim any human within 500 feet of it. They appeared to be 100 feet away at detonation. Yet, they walked away without a scratch. They didn't even get their bell rung.
At 40:55, off-screen there is the sound of the hammer cocking back on Max's handgun. Two seconds later, now on-screen, the hammer is not cocked with no further action by Max.
