^ Exactly.
Key West, it depends entirely on how tight.... err... picky the staff/parents are. If you have an OCD rule psycho they'll make a tadoo. OR if you've had a parent in the past make a stink and worry they'll get fired up again, then you might operate on better safe than sorry. If your school doesn't have an nuts who care more about policy than educating... or parents who are similar... or have students that would actually bring a weapon... then there's no reason for your school to be uber picky... you're very lucky!!
Never know, this school may have had some kid bring a watergun once... and had to deal with the parents going nuclear over their kid getting in trouble... so to avoid them screaming discrimination they had no choice but to be picky about this instance.
Honestly there's no way for spectators to know, and with privacy laws as they are there's no way we'll ever know. But I'm with LJ and Terrie... this is a rule about guns, not patriotism, military, this or that war, left or right, just guns. If the parents have a problem with it then they need to take a petition to the school board, not blatantly defy it just to prove a point, and in the process drag a kid into the middle of a media circus. Most parents are aware when their district has a no weapons policy. Guess there's a small chance that these weren't then I'd wonder about their participation in their kids' schooling... so many just see PS as free babysitting... but again, we don't know. But "I didn't know that was a rule" isn't a valid defense... and is a moot point because the child wasn't punished for violating it. He wasn't given so much as detention, never mind expulsion.
If he'd been punished, while I would be annoyed I couldn't really condemn them for following the policy they are supposed to enforce. It would bite, for the kid, but it would be the rules being in effect for ALL to protect all. But even then, I wouldn't see the need for this circus. Break a rule, get proscribed punishment, the end. The school didn't do anything wrong. Didn't target this kid. Anything like that. They treated him better actually than other kids who bring a toy gun to school. So what's their problem? Why would you want your child, your school, etc blasted all over the media... when he wasn't punished.
Only thing I can figure is that for them this isn't about guns it's about making a statement... and when their statement wasn't allowed to be made they threw a fit. But, again... we'll never know because they wouldn't ever admit that they used an innocent child for political reasons and the school legally can't say what happened.
Worst thing we can do if this is an attention ploy is NOT give the attention seekers what they want.
edit... Mo5... Seriously? They took them to a GUN museum then said they're bad? Wow, that's a new level of moron.
