It deals with red flags associated with school shootings. Let me also state that many schools do not allow students to wear camo, for the same negative view of camo.
That's an interesting list of "red flags", many of which,
in and of themselves, are completely harmless.
For instance, under "Boasting and Practicing....", it lists martial arts
and sharpshooter training. Does that mean that anyone who has
trained in martial arts, or shoots groundhogs at 300 yds. is a potential
school shooter? No, of course not.
Under "Loner", well, hell...that describes me almost to a "T". I also often
wear a long sleeved camo shirt that I've had for 30 years, and I've been known to smoke a bowl (or 5) on not so rare occasions. I've now ticked off five of the boxes. If you met me in person, you'd find that I'm one of the most easy-going, non militant old dudes you've ever met.
Put it in context..other than being a loner/stoner, wouldn't you think
that these are also the qualities you'd want in someone
going in to
stop a school shooter?
There are, indeed, things listed there that are, most definitely, red flags.
My point being, there's a lot of gray between black and white.
