Can I still be a cop if I have some undetected crimes?

I'm 18 years old have have wanted to be a cop for awhile now. But I have had some undetected crimes. I have smoke weed. I havnt since i was 16 years old. I have stolen a case for a iphone before and that was when I was 17 and last a girl hit my car in the parking lot at school once. She lied to me and told me it wasn't her. But I proved it was her and I got an estimate from a car place that it would be 250 dollars to get it fixed. She gave me 250 dollars. But I never got it fixed. The only reason I never gave it back because she lied to me when I confronted her. Oh ya when she hit my car. She drove off and two weeks later is when I found out that it was her. Should I be worried about any of these if I want to be a cop?

It's not a crime to accept a payment for property damage and not get it fixed. There's nothing you have listed that will prevent you from becoming a peace officer. You need to get the proper education and good grades without stealing anything and you have a good chance.

You have Nothing to worry about, go ahead be a
policeman, but be a good one, and I think you will
be a Very Good One, why because you realize your
faults and thats good.
Study hard and be professional in this career, we need
you.>>> if you are a bad one, they will take your
Donuts away for a week and then you will be sorry!
(Sorry about that last sentence, I could not resist)"LOL"
