so, and at stanford, you know, it was very interesting because here the encampment is just now coming back after being forced to end in february. but protesters have been there for four months with tents. why didn't it catch fire that time? what is the tipping point? why now? why the columbia one that kind of sparked everything? >> it's really hard to say what the factors are here, there is a history at columbia. of course. i mean, going back to the 1960s where you had mass demonstrations in 1968, in columbia, wanting the school to disengage from any, contracts or activities that supported the vietnam war, occupation of student buildings. and then those protests radiated through the country, hard to say why it's columbia again at the center of this, other than the fact that there is this large encampment and it has led to confrontations and arrests, do you think considerations should be different for private versus public universities in terms of what they allow of their students in the protests? >> i mean, i know they treat us, the media, differently in terms of access, but how about
