I'll say this...I like your style.

The real problem isn't showing the serial numbers. You have to remember that somewhere out there is a very political prosecutor. You don't know it yet, but this guy is your mortal enemy and he's just waiting to get any chance at an amount of control over your fate. That very political prosecutor doesn't have an ethical bone in his body. He's going to take every post you've ever made and twist it's meaning to suit his narrative. He's going to take every picture you've ever uploaded and he's going to interpret it's meaning to the jury. He's going to lie and slander you using your own words taken completely out of context. He's going to coerce anyone he can to lie about you and he's going to make you look like a rabid dog to a jury of 12 strangers that he got to pick and what's worse is that he's probably going to get a judge to put a gag order on you to keep you from asking the rest of us to help you. You don't have to look very hard to find real world examples of this happening. My point is simply to remind you that the second amendment is there to protect you from a corrupt government, be careful that you don't let that corrupt government use it against you.
