Humor-author's note

For my humorous piece I am arguing against guns on school campuses. I chose to do a comic of a preschool, Sunshine Elementary. All the 4 year olds are holding a gun and have ammo in around their waists. The shooting range is in the foreground with a teacher saying "I will give extra credit to the person who hits the bull' eye the most" and another teacher saying " does anyone need more ammo?". There is a rules list above the gun target that says everyone must be under 5 years old, own a AK-47, and be enrolled in Sunshine Elementary.There is also a sign that says BYOG-bring your own gun next to the Texas flag.
I hope that I have been able to display my argument without many words. This is my second draft but my drawings are still not adequate, yet. The only concern of mine is that I might be offending teachers, who might not necessarily be pro-gun either. I do not want people to react too sensitively because of the anniversary of Columbine being yesterday, and with Virginia Tech and Northern Illinois still recent tragedies, I do not want to hurt anyone.
