@chetibby.bsky.social Hey now. Just read your piece on incoherent violent extremism in the Jl of Policing, Intel and CT. Really good stuff. Finishing up a similar paper with my PhD researcher Morgan Shayler, and will incorporate yours. Appreciated your points about MUU not being a 'holding pen.'

Three climbers - left to right - Frank McCarthy, Mickey Gutwein, and John Horgan on the summit of Carstensz Pyramid, west Papua.

Temporary escape from the insanity. Summit of Carstensz Pyramid, west Papua, about 48 hours ago. Highest peak in Oceania and one of the fabled Seven Summits. Very technical climbing and lucky to have had great conditions. L-R Frank McCarthy, Mickey Gutwein, me.

Hello new followers. I’m John Horgan, a professor of psychology who studies terrorist behavior. Don’t believe anyone who says they know what is going to happen next. Nobody does. Believe the Trump administration least of all. The informed voices are out there. Seek them out.

The University of Texas system has voted to limit 'controversial topics' in class. Where's the academic freedom?

"A faculty member is not going to be able do talk about current events without risking being fired. What kind of education is this?"
