Re: Career in Law Enforcement with Juvenile Record
What you describe is not likely to be a legal bar to employment, but an employer may take this history into account in the hiring process.
However, given the time and what you intend to have accomplished by the time you apply you should be good. Reliable work history, no serious run-ins, schooling, all those will go towards showing that you have matured. But, it will dog you. All you can do is keep plugging away and touting your accomplishments, not what you once did.
