Don't mind bourbon, shes abrasive, but means well! Honestly though, in my opinion, if you're serious about being a cop, I would think drug conversations would be invaluable to you. You should try to learn as much as you possibly can about the subject. Even if it makes you uncomfortable, some of our members can teach you a lot about the way it works. How its made, trafficked, cut, sold. . All the little tricks people use to hide it, distribute it, and avoid detection from guys like your dad.
Personally, I respect your endeavor and I wish there were more good cops out there fighting the good fight. Its not a fight against drugs, its a war. People are killed over it every day, namely, amphetamines. They are the plague of our country. Learn as much as you can about it, it could save your life.
Thats just my $0.02.
