Based on this info and the info from previous articles; the shooting occurred in South Old Town, went into North Old Town ("Authorities later found the cab Laboy was looking for driving northbound on the George Washington Memorial Parkway and Slaters Lane") and then back into and through South Old Town before ending in Fairfax County on/near Fort Hunt Road?

If the above timeline is correct, have the police reported on which route he took going from the Slaters Lane area back through and out of Old Town? I'm curious as to whether he went into Fairfax County via the GW Parkway or Rt. 1.

How is this man allowed to drive a cab with 17 traffic offenses?

Taxis in Alexandria are completely unregulated. Drivers and companies are subject to a relatively thin form of cosmetic licensure, but enforcement is based almost exclusively on spot checks by hack inspectors. Complaints to the APD hack office about taxi driver competence and geographic familiarity, driver inattention, taxi conditions, and especially taxi dispatch practices typically are referred back to the taxi company. One complaint we filed resulted in the hack office providing my full name and office number directly to the driver of the taxi, which was remarkably unhelpful. No matter what the complaint is, the hack office says "that's not within our jurisdiction" -- which is completely incorrect and is a self-serving, lazy misread of the ordinances and regulations. With only one exception that we've ever seen (concerning a direct, persistent, traffic safety threat), it would appear that Alexandria's taxi drivers know full well that they can get away with anything.

I hope that something positive comes from this horror and that the Alexandria City Council and police work together on regulations and enforcement to prevent anything like this from happening again. I would like to see very tough and fully enforced background checks for cab drivers, and loss of licensure for tax companies who hire drivers with traffic or other serious violations.
