J6

I keep seeing and hearing bits and pieces about the congressional hearings around J6, and It's raised some questions. 1. It seems as though the Justice Department is actually conducting an investigation of J6 as well. Isn't DOJ better equipped to conduct this sort of investigation than the house? 2. Isn't the DOJ actually in a position to bring criminal charges and punish those found guilty? 3. Isn't the DOJ staffed with (theoretically) non partisan, non political, investicgtors and lawyers who are actually trained in both US criminal code, as well as in how to do an investigation? 4. Given the makeup of the J6 committe, in what way is this an impartial panel that is deciding the outcome? 5. What exactly are the rules and how are the accused guaranteed due process? 6. Do the accused have actual defense counsel to represent them and advocate on their behalf? 7. Who on the J6 committe has actual experience in any sort of criminal investigation? 8. Aren't the members of the committe, and their staff, by definition both partial and partisan? 9. Don't these congress members have anything better to do, like legislate?
