There is no evidence stating that either the gun or scale were even used for the weed - which is probably why the charges got dropped down. Just because they found a scale in his apartment, doesn't mean it was with the weed. I know tons of people who use scales for cooking - specifically athletes and those looking to be in top shape. Hell, I know people who use scales for their coffee. Many of those people also have guns. I'm sure I could combine three random objects around your house and make you look badly too.

Everyone is using pure speculation to judge this kid... to quote W: "Too often, we judge other groups by their worst examples - while judging ourselves by our best intentions."
