Depends on the kid. Wouldn't be my first choice for youngings.
But in general, I have zero issues with it.
I have no kids, but working with kids was a profession. I would teach kids not to get in a car with strangers, but also acknowledge that they can get in the car with their parents.
Meaning, kids can tell the difference between good and bad guys,and can
translate those themes.
Besides, all silhouettes are bad guys.
If we are teaching kids the basics of safe firearm handling and should be teaching them the consequences of firearms and that they are deadly, then the target could be inconsequential.
But I'm also a guy that won't let kids point toy guns at people, so maybe I'm a hypocrite.
