Brickell and Downtown are becoming hood

Is it only me who is noticing this? The quality of people and safety in this (very expensive) area has gone WAYY down despite prices skyrocketing since Covid.

Just this month alone we had a homicide in once of the nicest buildings, where a psychopath slipped past security, would randomly try to open doors, slipped into a random apartment and killed a 17 year old in cold blood. A few weeks later, only half a block down, a woman was thrown off a bridge into the Miami River and died. A few months ago, someone broke into an apartment of someone i know, in a nice building with security (a pretty much useless commodity tbh) while they were sleeping. Took a laptop and took pictures of credit cards in the kitchen. No one has any idea how they got in. Police and the building did absolutely nothing, not even change their SOP or add Access Control to the elevators.

I feel the situation became even worse with the constant DoorDash and food deliveries, with randos contantly coming into buildings and floors.

I am very familiar with the area and the apartment buildings there. They ask for your entire life story, bank accounts, where you work, your income, etc. Not a simple credit check. With the amount of hoops you have to jump over to live there, the people in the buildings are trash. Some look like straight up druggies or drug dealers. People are super rude, loud, and confrontational. No one cleans up after their dogs and dogs pissing in the elevator is a normal occurrence.

Maybe im missing something? I've lived in Miami 15 years and dont remember it being like this even 5 years ago.
