So asks the brother of one of the Fort Totten crash victims (http://voices.washingtonpost.com/dr-gridlock/2010/07/family_what_good_will_this_do.html)
And people wonder why they want WMATA to be federalized (I've had people want the US DOT, NTSB, even the FTA to assume operations). As bad as it may be, there at least is the illusion that some accountability may exist.
It is strange that all of these safety organizations can't hold Metro to the fire to make sure they implement the various safety fixes properly.
Neither the NTSB nor the TOC has any method by which to enforce safety regulations and such, nor does the FTA. This goes back to when subways were a relatively new idea, and it was feared that if they were prone to all sorts of regulation the way planes and railroads are, no city would want to build them.
