People are going to drive this dude to suicide.
In all sincerity, this guy is going to regret what happened for the rest of his life without the world shaming him. He's a deputy, not someone trained to make a solo run at a dude with an AR-15.
It is cruel to shame him for his actions, but he was an armed sworn police officer with a duty to uphold the law and maintain order. He was the most trained and capable person on-site to mitigate damage and save lives, and he chose to stand outside while children were getting massacred inside. He didn't need to chase down the shooter and take him down like a scene from a Hollywood movie - many unarmed teachers and students saved lives that day without trying to take down the shooter. Some gave their lives doing it. I'm not going to call him a bad person, but he blew it big time, and his actions (or rather, inaction) are damaging to his profession and the thousands of school resource officers out there who would've done the right thing if they were in his shoes.
No, they do not.
What this example shows is that the whole 'good guy witth a gun' NONSENSE the Republicans and NRA socks like to peddle is a crock of santorum.
