On CBS’s FBI Most Wanted (S2 E4 January 19, 2021), a woman steals his father’s gun from a lock box at home and attempts a mass public shooting. The father attempts to justify owning the gun to protect his family, but the message is obvious: parents may think that they have a gun for safety, but the gun will be used for bad purposes and they should be afraid of guns in the home even if they are locked in a safe. The lead FBI agent even says that it is “wise” that they have the gun locked up, ignoring that locking up the gun can make it more difficult to use defensively (see here).
Since this type of event is indeed possible, this wouldn’t obviously show bias by itself, but CBS’s FBI Most Wanted or FBI have no offsetting examples of civilian-owned guns being beneficial. This episode is very similar to an episode of FBI in 2019 (see here).
The obvious implication is that despite the evidence to the contrary, people shouldn’t own guns.
