2) Only "hundreds" of people are involved in the latest demonstrations. [link|http://news.bbc.co.uk/2/hi/south_asia/4547413.stm|BBC]:
In Baghlan, officials said hundreds of demonstrators took to the streets.
They said five people had been arrested and that explosive materials were also seized.
Realizing that numbers can be shaded either way, it does not seem to be a major showing of discontent at this point. Don't give up on millions of people due to the actions of a tiny minority.
Yes, the US should get to the bottom of what happened there ASAP, and if it happened, then those who did it should receive training on what is and is not permitted in interrogations and why. If they broke the rules they should be reprimanded or worse and transferred. If they didn't break the rules, then the rules should be changed.
Crap like this will always inflame people who hear about it, to varying degrees. Unless the US plans on holding everyone there forever and never allowing communication from Guantanamo or inspection of the facility, then they need to end practices like this. If it occurred.
Leaving Afghanistan to the militants isn't an option.
