In Florida, it is legal for a person to carry a weapon, whether openly or concealed, at his place of business. It is also, as a matter of law, considered non-lethal force to merely point a firearm at someone. It is lawful to use non-lethal force to protect property or to prevent a crime. In other words, what the store owner did was completely legal.
So why is the Orlando media posting the same article with this misleading headline?
Man pulls gun in confrontation over gas pump skimmer, deputies say
If one were to read the headline, you would think that the entire incident was some sort of road rage argument, and not a store owner performing a citizen's arrest on a criminal. It is subtle things like this that the press uses to influence public opion against guns and gun owners. Why not make the headline "Gunman interferes with man attempting to earn a living" and just go full bore with the propaganda?
As a side note, the man who is accused of the crime is not a US citizen, and has already been convicted once of credit card fraud.
