The precautions taken indicate that the store was probably a (may I say it) "bad" neighborhood, and making lots of money was the reason for keeping it open and exposing employees to harm. Greed. Sheer greed.
I wonder if this pharmacist won't suffer pangs of conscience after he recovers from shock and post trauma problems. After all, he has killed a poor young minority person, who wanted money and drugs.
The robbers weren't dangerous because as some lefties indicated on another thread, they are stupid and inept. They were just like those fellows who tried to bomb the synagogue. They were nature's noblemen, who should have been rehabilitated.
The weapon of choice used by the pharmacist indicates that he was not fully prepared. Either he needed a 22 long, which would penetrate most skulls, and then circulate and destroy brain tissue, an assassin's weapon of choice, or a larger caliber weapon.
The poor minority robber was apparently ill-trained and didn't really know how to use the weapon, which was probably meant more for intimidation. And besides, the pharmacist probably in some way provoked the robber to start shooting. The pharmacist should have been given victim training.
Maybe the robbers were emboldened by the stimulus package, and thought that they should also get theirs.
It's a compelling case to convince victims to be compliant and if the robber starts shooting, just beg for mercy. That way, you won't spend sleepless nights seeking forgiveness for shooting a poor young man, who needed money and drugs, and possibly could have otherwise lived a happy and productive life. Why I bet he had children and a mother, who would tell you that he is "a good boy," and that this was an atypical misstep. He probably also did poorly in school, and the school was derelict in providing him with sufficient self-esteem.
Alas, "society" has failed and not the miscreant.
