I've lived mainly on Capitol Hill and it's a safer and "nicer" place than it was back in the 90's. I had drug deals happening on corner outside my house back then, the neighborhood is great now. I also lived downtown, where Pike St. between 1st and 2nd Aves was horrendous with homelessness and drug use. Clearly much nicer now. The Central District (the other neighborhood I'm most familiar with) has also undergone huge level of gentrification since then, is much "nicer" place to live than it was in the 90's.
Yes, homelessness, and drug use and mental health issues are big problems, and I'm not sure the city has taken best approach to them. But it's easy to criticize without having better answer. The sensationalist ranting I hear sometimes in media and in personal anecdotes seems pretty misleading.
Compared to Orlando and Salt Lake City, Seattle feels about on par to me with regards to safety and the homeless problem (adjusted for the much higher population & density). Which is useless information because it is an anecdote, but the best way to bring data into a conversation is a lot of useless competing anecdotes.
Ballard? I’m not even sure where it being dangerous would come from, maybe getting run down by a bad Norwegian driver? Checkout Cops in Ballard: https://m.youtube.com/watch?v=hGlDVmBLibg
(Yes, that is Bill Nye)
Ballard is much worse. It's gone from an enclave of retired scandy fishermen to hip neighborhood with a thriving walkable main drag. Because much of the street parking is still free the homeless living out of barely functional vans and rvs can live without hassle and attempt to panhandle on the drag. I imagine that at least some of those vehicles are also essentially drug emporiums further concentrating the homeless population that is hooked. ... Still not as sketchy as the u-district in the 90s though.
I worked at 3rd and pine McDonald’s in 94-95 (one of the main hangouts for Seattle’s homeless population back then), and downtown was a lot more sane back then. The policing was much more aggressive than it is today, which I think had a large part to do with that.
