This is behavior that gets people killed!! Call the police and get a tag # if possible. For all he knew that could have been the foreman of the site getting some stuff for another construction site.One day, he said, he noticed a man across the street stealing from a construction site and decided to stop him.
He grabbed the gun and ran outside, firing one of the blanks.
A struggle ensued, and the man knocked the gun out of his hand and ran. The police officer who arrived at the scene a few minutes later had some advice for Virtue.
There was no threat to anyones life, but Rambo decides to charge out with his "blank" gun... geez
ETA:
This reminds me of a 60 something gentleman in my CHL class. The instructor was talking about your options when you witness a property crime, much like the one mentioned above, when the older gentleman asks " If we see them doing it then can we make a citizens arrest?"
You could have heard a pin drop. Even the instructor was taken aback. At lunch we started a "how long till he gets killed sticking his nose in a domestic disturbance pool"... I took 9 months. (I hope he's OK)
Owning a handgun and/or having a CHL doesn't make you a LEO or give you any additional powers. Use common sense, don't put yourself or others in a potentialy life threatening situation when you aren't 100% sure of what is going on.
