Innocent until proven guilty and all of that. But based only on the facts in this Globe article, I have a hard time thinking of too many conclusions to which one could safely jump beyond the obvious one.
It will be interesting to see how this plays out, not only in the courts but on Beacon Hill. Before last year's Wilkerson / Marzilli / DiMasi Corruptapalooza, the Beacon Hill modus operandi in such situations was tried and true: circle the wagons, 'no comment,' business as usual. Then those three bombs went off, messily, inside of that tight circle... and now a relatively new Senator with, er, driving "issues" might just pay an accumulated political price.
UPDATE: The Senator has apologized for his hit-and-run. He "panicked." Having done some prosecuting in Massachusetts myself, I can say that generally an apology, no matter how sincere, generally does not do it for Joe-on-the-street. I doubt it will make much difference for the Senator either.
