I think that posting those messages on You Tube was just plain silly.
If you really want a response from the mayor, send her a typed letter, by regular mail, which asks for a specify reply or explanation from her.
The issue isn't really whether the mayor cares about handicapped citizens. It's more about whether Baltimore City vehicles are needlessly, or inappropriately, violating parking laws, and whether this goes on on a regular basis.
For instance, was that truck even on City business when it was parked there? Did the driver use a handicapped spot because it was the only space wide enough to accommodate the vehicle? A City truck should have more leeway about where it can be parked, but only if that is necessary to accomplish City business. I'm sure that City vehicles may also double park, or park by fire hydrants, from time to time. To some extent, since the City makes and enforces the traffic and parking codes, City vehicles can be parked just about anywhere with impunity.
A few years ago, the very large municipal parking lot for my office building was partially ripped up in order to replace some underground pipes. The main area ripped up was where the handicapped spaces were located. The parking meters were pulled out, the ground was dug up, and the whole handicapped area was taped off. But then, all work suddenly stopped, nothing more was done to the area, and this went on for weeks on end with the area remaining unusable for parking during this time. Since no other temporary handicapped spaces were provided during this period, which went on for about two months, parking became a nightmare for me. Often I had to park at a very far distance from the building and I was in agony walking back and forth from my car.
I contacted the mayor of the municipality involved and complained about the situation. While the mayor apologized about the situation, and about causing my difficulties, he maintained that work schedules elsewhere, and a lack of sufficient manpower, had delayed the work in the parking lot. He offered no sufficient explanation for why additional temporary handicapped spaces could not be provided elsewhere in the parking lot, and he did not seem to genuinely appreciate the mobility problems of handicapped drivers.
Although I could have pursued this matter further, I really felt it would be a waste of my time and energy. What was going on with the parking lot was the result of extremely poor planning--they had started a job they could not continue to work on for weeks and weeks. In addition, this municipality was known for "abusing" drivers in other ways. Parking meters in this same lot were routinely broken and not replaced. For instance, a parking meter which registered 6 hours of remaining time, when the driver parked the car, would run out in under 3 hours because the internal clock was malfunctioning. Drivers, who had no way of knowing the meter was malfunctioning, would return later to find their cars ticketed. The municipality, which was generally rife with corruption, never fixed these meters because they made more money handing out parking tickets.
The municipality's disregard for handicapped drivers in that lot was really no worse than their disregard for all drivers, they just didn't give a damn, and they simply did what they wanted. In this instance, I was not a resident of this municipality and I felt it would be futile to try to make a bigger issue of this particular situation with the handicapped parking, given this notoriously bad municipal administration. I did successfully fight a parking ticket I received at one of those broken meters, but that didn't succeed in getting the meter fixed. I chose, instead, to discuss my parking problem with the management of my office building, and they kindly provided me with a sticker which allowed me to park in their small private parking area adjacent to the rear of the building. While this was a slightly longer walk for me than the handicapped parking in the public lot would have been, this area was unmetered, so I had one less problem and that was a more than decent trade off.
But I did get a response, of sorts, from that mayor, I was not ignored. And I can't think of any instance when I have not gotten a response from any public official or CEO I have complained to about a matter. I know how to complain in a manner which gets me a response, and generally a more than satisfactory response. Had I really wanted to pursue it, I know that I could have publicly embarrassed that mayor into speeding up work on that parking lot. This particular battle just wasn't one I felt like devoting much time to--and that mayor got ousted in the next election.
So, if you want to complain about something, do it in a way which is more guaranteed of getting results. An e-mail, which really isn't asking for a specific type of response, is not the way to do it.
