An Illinois dad threatened to send his brother armed with an AR-15 to an elementary school to teach his son’s bullies a lesson, authorities said.

Paul Chapman, 43, wrote in a Facebook post Thursday that his brother would go to Robinson Elementary School in “full uniform” with the semiautomatic rifle to “make an impression” on the first-graders who picked on his son, Cook County prosecutors said.

Chapman’s kid was pushed into a bookshelf and had to be treated for a head injury, the Chicago Sun Times reported.

Chapman’s menacing social media post had included an image of his brother in a military uniform.

On Friday morning, school officials were alerted of the threat and six elementary schools were placed on “soft lockdown.” Authorities said no students were ever in actual physical danger.

Now THAT my friends is a trophy you get from loving unclean women the likes of which these eyes have never seen.

Fucking terrible timing to have an outbreak too.  The day you tell your kid to take an AR-15 out of the closet and murderate all the bullies at school, you get booked and your mugshot includes some painful looking open sore on your mouth.

Maybe put more effort into getting a prescription and less into encouraging your kid to be a serial killer.

Don’t throw that pic up on Match.com unless it’s in the “herpes” section.  Then you’re golden.
