If Cal is number one, that doesn't say much for American education. (P.S. I'm a Cal grad and can recall the acrid smell of teargas as it roiled across the campus in 65.) You are right, a check of those arrested in the major free speech clash (900 or so) indicates that fewer than 30 were born in California, and the vast majority were New York red diaper babies.
I was only in elementary school during the 60s but remember all the crap going on.....you are right, there were so many out of staters that just came to Berkeley to do drugs and start trouble.......most didn't even go to the university.....however, if you look at the ratings like in US World News & Reports....they are still one of the best universitys you can go to education wise....have the most top 10 grad programs and most Ph.D's of any US university. I try not to confuse the education there with the liberal idiots that the city attracts...
