Not made up at all. In large parts of the US people leave guns in their cars all the time. It ends becoming one of if not the largest source of stolen guns.

You obviously didn't Google this, since there are states in America where the people are PROUD to show off the guns and gun racks in their trucks. Yes, they proudly display these guns. (Texas, looking at you)

> did you feel really smart putting that totally made up "because people often leaves guns in their cars" in there?

I can’t tell if you think people obviously do leave guns in their car, and GP should know better than add the phrase in, or, that nobody does, and GP should know better.

I can tell you have seen people do both in different parts of the country.
