if youre a student in college (or these days highschool) and the one weird kid keeps talking about how he hates everything. and you're getting those kinda vibes from him that he really might do something. yall find out he bought a gun recently. if u called it in, you would not be ok with the police saying "we knocked on his door and asked him some questions, he said he doesnt know what yall are talking about. theres nothing we can do.." you would not be ok with that. you wouldnt feel any safer. especially if he came the next week and did what these psychos keep doing.
