he was being arsey with the standard campus security people, whose "random" id check (he's of iranian descent) showed he'd forgotten his student card, so they wanted to evict him from the library.
the coppers came, and while he was eventually walking out (amidst much shouting) they grabbed him & tasered him
they then told him to stand up or get tasered again (which they obliged with), ignoring the ~15 minute recovery time on a 5 second "drive mode" blast with a police issue taser
see above paragraph for shock #3
they then handcuffed him, started dragging him out, and tasered him twice more in the process
