Steve, I don't have the time that a lot of these folks do, and I certainly don't hire people. I'm just a simple rookie trying to learn the job.
I too, am 21 years old and I posses many of the same details that you brought to light. I too had blemishes on my record that I wasn't too proud of.
But.....I never mitigated what I did, and I certainly never "chalked" it up to the fact that everyone does it.
See, the whole "everyone does it" mentality is VERY juvenile....and really furthers Curt's reasoning that you are not owning up to your decisions in life. True, there are kids out in society that smoke dope, deal drugs and party non stop. Those people are also not applying to be an LEO, something that requires immense responsibility.
I'm no alter boy by any means. I'm a stubborn, PITA guy who went through the process admitting to everything and taking responsibility for all of my decisions. Yeah, some of them weren't great, and yes I sweated a lot during the process. But they were my decisions and for better or worse I stood by them.
Of course, you can do it your way and say that everyone around you does it and that excludes you from any responsibility. Lets see if your way works.
