"He killed himself, you baboon"

59. By moving to him they changed his focus and that stopped him

This is where standard active shooter response tactics aim for. The lesson learned after Columbine was that you can't just contain and wait for SWAT where there is someone actively shooting because doing that let's them kill much longer.

So what every cop is trained to do now is move to the location as fast as you can. You don't wait for special weapons to arrive, you don't wait for the guys with heavy body armor, as an individual officer you grab what is available to you and as soon as you have 2 or 3 officers on scene you move toward the sound of the shooting. Your intent is to get to that shooter as fast as you can and disrupt his actions. Maybe you can shoot and stop him. Maybe all you can do is make him aware you are there and get shot at, but if he is shooting at you then he can't be shooting at anyone else so that still disrupts his killing.

And the pattern for these types is very clear, overwhelmingly as soon as anyone, law enforcement or not, shows up who also has a gun and will shoot back they either kill themselves or just give up. It is very, very rare for them to continue trying to carry out their plan once armed resistance is felt by them.

Yes, they stopped him. The LMPD and security there didna textbook job of moving toward the sound of a shooter and disrupting his plans and making the fact that resistance was there known. That stopped him and led to his decision to kill himself.
