1) The deputy should have used the ladder the perp used.
2) you are correct, at a minimum you fire shots in the air to alert everyone.
3) We won’t talk about the deputy simply radioing the security detail. They are all in sync with the SS, they literally do this all the time everytime a prez or candidate comes to town, they pull state and local police from surrounding communities. Forgot the point of fleeing the perp. Most people, even LEO, are hesitant to shoot at people, just human nature. What not normal is not shooting warning shots and doing everything possible to alert the security detail.
“The deputy should have used the ladder the perp used.”
In an ideal world, yes. But it looks like a large building and that ladder could have been anywhere. I think kudos are in order for one officer quickly hoisting his partner up to the roof without wasting time running around to find a ladder. That was quick thinking.
But NOT firing warning shots was a nearly fatal mistake. Even his partner on the ground could have fired warning shots.
