There have been several incidents of muslims driving into crowds of people as well.
Most, if not all, murderous terror acts committed around the world can trace their roots to Islam and Muslim extremists, no matter which country or continent and we can now lump the Muslim Brotherhood that is in charge in Egypt, as a sponsor of terror, for they are killing Coptic Christians by the droves. We just don't hear about it at least not from our own MSM for they are loathe to point the finger at Muslims.
It is so difficult to understand as the media, academia and Hollywierd, are so pro-Muslim yet when or if Muslims and Sharia law became prevalent in this country, wholesale honor killings, slaughter of homosexuals and clamp down on all pornography vendors (think Hollywierd) as well as nonsensical college classes on or about sex, would stop immediately!
