This was given to me by a friend today, who had visited a recent Mardi Gras parade. His girlfriend found it while randomly scavenging around.
It originally had a red rubber band on it, but that ended up cut and lost, hence the regular rubber band to keep it closed. Thankfully it was never used though.
Perfect awareness would be knowing what is and what is not a threat. Paranoia is seeing threats everywhere, even where there is no threat.
Yes, that is a very dangerous object your friend found. It can seriously harm someone. What evidence did you find that makes you think it was being used for something nefarious, other than the location? Normally someone would find that and think "wow, some people are so dumb and careless to lose a dangerous item like this and leave it laying around!" You seemingly jumped to the conclusion that it is intentionally being used to hurt people.
Without talking about how dangerous the arrowhead can be (we are aware), or where it was found in relation to a parade route (I'm guessing it isn't someplace where the public is banned from entering), what makes you think it was an intentional act and not just the carelessness of someone losing it?
