Community college students are not very smart on average, so it's very difficult to teach proper computer science. And community college professors are generally older and not very fad driven so it's unlikely they will effectively teach the Rails-Mongo-Heroku stack (complete with unsanitized inputs).
The way the various code schools get around this problem is to hire young hipster coders (as opposed to a former academic with a Ph.D.) to teach for a year or two. But that's not really a model which one can reasonably expect community colleges to adopt.
Additionally, the post-code academy hiring model isn't well suited for CC's. The hipster who taught GA/hackerschool/etc for a year or two becomes part of the alumni network and is likely to hire some grads. That doesn't happen at community college - even the temporary faculty just go to become temporary faculty elsewhere.
