So after school today I was waiting at the bus stop sitting down and on my phone. After a few minutes when nobody is around a black car with tinted windows and big rims pulls up around 15 feet down the street from me, a mexican kid gets out trying to be quiet about it and i barely hear the door close. He started walking towards me hand in his hoodie pocket with a dirty look, obviously I had a bad feeling about this so I put my phone in my pocket and got my hands ready(didnt have my knife on me). So he's walking up to me( he seemed a little nervous) then he stops a few feet from me, pauses and then hand still in his pocket(kind of looked like something was printing) stutters and says "uh you know what time the bus comes". When i went to answer he basically started walking around in front of me not listening to anything I said then he started walking away, looked back and kept walking towards the direction the car he got out of pulled off to. Now I told my brother about this(used to gangbang but not anymore and has robbed a few people in his past) he said he was probably a send off who his "boys" told to rob me but he got scared. He said if he got to nervous to rob someone he would have said the same thing. Anyway, it was kind of suspicious and nerve wracking that I could have been robbed at gun point. That being said what are some items I can carry for self defense that are legal to carry federally ? I dont care if its not allowed at school and I will look up my state laws myself. Sorry for the bad grammar im in a hurry to get to school.
