On Walgreen's firing of employee defending himself

From comments seen at Uncle's 

Here’s their response:

“Thank you for contacting Walgreens regarding this matter.

Thank you for contacting Walgreens to share your comments.”

In particular, when law enforcement strongly advises against confrontation of crime suspects, I wonder what ideal world they live in? As a peaceably armed citizen, I would not go looking for trouble. I would not actively seek out a criminal and confront him or her. That is the law enforcement's job, to confront, arrest and convict criminals. I commend them for doing that job. It is many times thankless & dangerous.

However, when a criminal actively confronts an otherwise law abiding person, the victim of the crime is forced to confront the situation unfolding before them. Law enforcement's recommendation about avoiding such confrontation has just gone pear shaped, the second the criminal introduces the threat of physical violence to the confrontation. How is it to be avoided? The criminal is demanding something of you, your property or property you're responsible for, your acquiescence to his activity, possibly he even wants to take your life.

A proper response would be to apply violence in greater force with the explicit aim to end the threat.  Sadly, many business' and lawyers do not see it that way in today's society.
