So, I've been in Vancouver for the best part of the last two weeks, for work. Obviously, from a density and vibrancy point of view, it is borderline silly to compare the two cities. One thing I've made a habit of, though, is actually screening for things I believe are interesting to help Edmonton's downtown, etc.
It includes fixing on " details" and one thing that really struck me hard is the RIDICULOUS amount of homeless, drug users harassing people, folks who I've felt fairly uncomfortable to be crossing paths with (and boy, it does take a lot to scare me... Rio gives you traumas that will take decades to heal)... In general, a lot of the same thing we complain so much about in Edmonton, probably just as much, if not more. The only tangible difference is the fact that there's so much more people out in the streets that these folks become somewhat invisible, or at the very least completely ignored by the vast majority of people around. I also didn't see a single beat cop patrolling the streets (and barely saw a couple of police cars around)
Not to deny that Edmonton needs to better address crime, especially in the core, but I really think we overblow it a lot, because these problems are that much more noticeable due to our lack of residential density.
