A father in the U.K. was recently questioned by police after posting picture of a T-shirt on Facebook (video below).
Martin Gillingham has had disagreements with his autistic son's school in Westbury, England, and believes the school filed a complaint about the T-shirt with the police.
He told the Daily Mail, "I just think they're trying to be vindictive and discredit me because I am outspoken in the press about the school."
Gillingham doesn't own the T-shirt, but posted an image of the clothing that read: "I may seem calm and reserved, but if you mess with my kids I will break out a level of craziness that will make your nightmares seem like a happy place," reported Metro.
The T-shirt also featured drawings of two guns.
In addition to the picture of the T-shirt, Gillingham wrote the caption: "I think I might wear this to the next parents evening (at the school)."
In response to the incident, the principal of Matravers School said in a statement:
"We have a clearly accessible and transparent complaints policy which we always encourage parents to use when seeking to resolve a concern.
"As a school it is vitally important that we focus our time on the education of our students."
