Of course, this has nothing to do with Islam, just with mental problems

There's never a connection between the so-called 'Religion of peace'  and a guy trying to strangulate a police officer and screaming 'Allahu Akbar':

Other police officers saw the events on the video surveillance system and rushed to save their colleague, who had been thrown to the ground. His assailant was said to have a history of psychiatric problems.

Of course, every terrorist has some 'psychiatric problems', as usual, and all these attacks have nothing to do with the religion itself. And that 'psychically deranged' person has almost managed to become elective for 72 virgins:

“The doctor who treated him (the officer) said that just a few seconds more and it would have been too late,” Michael Philippart of the SGP FO police union told L’Est Républicain, a newspaper.

Remember that each and every time a person praises Allah either before or after killing a muslim, a heretic, an apostate or an 'unbeliever', it only has to do with mental problems.
