I live in a college town(UGA- University of Georgia), and I went to school here some years ago. I'm not saying that random crime doesn't happen, it does, but the vast majority of the bad things that happen to our young adults here happen because they put themselves in situations that compromise their personal security.
To anyone going to college:
Be smart. Use the campus security vans, buses, etc. to travel after hours if offered. If you're worried about walking to your car at night, call campus police - they'll be happy to provide you an escort.
Be responsible for your own wellbeing!
The vast majority of cases that I see here are young folks who become impaired through alcohol/drugs to the point that they don't know what they are doing, making them easy victims for those who prey on others.
Have fun, experiment all you like, that's what these years are for, just don't blame others if you put yourself in a situation where you can be exploited. Understand that you are now in the real world, and it's a nasty, dirty place sometimes.
Understand that when you choose to use alcohol/drugs that you are choosing to alter your normal mindset, particularly your inhibitions. Find your limits, and stay within them, don't depend on others to protect you from the bad things that may happen when you exceed your limits.
Keep a cell phone on you at all times, don't go off with folks you don't know. Don't try to walk/drive home from the bars at 2:00am drunk, call a cab. UGA has a comprehensive policy to get all students home safe, don't be afraid/ashamed to call the "safe ride" numbers.
Understanding that you alone are responsible for your safety, not the police, not your friends, is the first step to remaining safe.
To the OP:
Be aware that firearms are prohibited on most campuses, and breaking the law by carrying one puts the student in a bad legal position, regardless of your personal views. College students are no longer minors, for the most part, (over 18) and will be punished as adults for illegal actions without regard to their parent's views on carrying a firearm.
