Third-year medical student or not, I'd say someone was trying to make news near the anniversary of 9/11. Psychotic Muslims can be so sentimental.
Zorkot, a third-year medical student at Wayne State University, was allegedly armed with an AK-47 assault rifle and dressed in black clothing with camouflage paint covering his face when he was arrested Saturday in Hemlock Park. According to police, Zorkot was observed attempting to leave the park in a black SUV after officers had received reports of a man carrying a rifle in the area.
Zorkot's website leads me to think he never attended an accredited design school. Also, his personal photo gallery takes an odd turn of theme just before his arrest (newest pictures on the top).
