I don't think I grasp your simile; what is the argument about an innocent schoolyard kid with limited power to harm? Are you just implying that congress has an apparently limited ability to affect USG Intelligence operations through oversight, or are you saying something more than that? Do you think the executive branch/intelligence community should be actively surveilling the legislative branch? I'm not understanding what you're saying here.
I've been drinking a good bit with dinner. When I want people to not ignore my stupid comments I make them a lot longer, sorry. The simile is, of course, that if given the power I would be spying on the Senate. Because they're interesting. People say children are innocent when in fact their crimes should be viewed as a percentage of their capacity to harm -- both numerator and denominator are small, which does not mean the resulting percentage cannot be large. Etc. Ignore me.
