Uhh yeah it kinda is nobdy likes to be around cops that much. Atleast where i live thats how it is. Maybe where you lived they are a respected member of society but where i am they are duches.
Is everyone a criminal where you live or something?
Of course people are fine to be around Police Officers. You're a handicap if you decide to just hate police officers because they police.
All of the Police Officers I know and have met are just normal people. Just because they put on a Uniform and actually try to protect people and enforce the law isn't a reason for them not to be liked. I'm pretty sure Police Officers have as many friends as people in other lines of work.
More-So-On-Topic: I don't think you should worry too much about not knowing what you want to do.
So long as you manage to focus on your schooling and get things done, opportunities will arise that will work out for you. And, there's allways time to get a job. Just focus, really. Education First, Jobs second and Family third. No need to cross a bridge before it arrives.
