There are so many wrong lessons here I hardly know where to start. There's a kid who checks that his mom is peacefully reading a book, then goes upstairs to (presumably) her room and opens her chest of drawers to find a gun (very much not safely stored). Without checking whether it is loaded or if a round is in the chamber or the condition of the safety if the gun has one, he puts it into his backpack without a holster or other protective covering and takes it to school with him before pulling it out of his backpack and putting it on the teacher's desk and asking the teacher to get rid of it because "he doesn't want to have a gun in the house."
Leaving aside the many insanely unsafe gun handling practices in this propaganda video, he's stealing a gun from his parents and taking it to school in order to turn it in to someone who (just based on profession!) likely has no idea how to handle it safely or dispose of it legally. Not to mention the school itself is a gun free zone. So. How many laws did this kid violate?
1) Felony theft of a firearm. Most gun felonies are 10 year federal crimes. 2) Gun-Free School Zone laws. $10,000 fine and 5 years. 3) Carrying concealed without a license, depending on state laws. 4) Illegal transfer of a firearm without a background check, depending on state laws. 5) The teacher may be liable for receiving stolen property. 6) Arguably reckless endangerment of the students and teacher, brandishing, etc. 7) Aside from the above, the student will undoubtedly be immediately expelled.
In addition his mom (and/or dad, who is never shown) will be vulnerable to criminal attack and may get in trouble for their unsafe storage. If either of the parents are police officers, military, or security, the gun may not even be theirs -- meaning they are in trouble with their jobs, and may be legally charged or fired.
This video is stupid propaganda encouraging kids to do things that will get them in serious legal trouble even if they do not accidentally hurt themselves or those around them.
