I just moved to Portland and I live in SouthEast (where this article is talking about). It was a shock seeing guards dressed in the same kit I wore in Afghanistan. They're not exaggerating the homeless situation here either. There's tons, and many of them are addicted to fentanyl or meth.
The political situation is exactly as they described. The county and city in Portland have a weird relationship. They're both "Progressive" but fight over what to do and how to spend money routinely. That's how we got the tents. It's incredibly cold in Portland and we don't have sprawling shelters to go to; most people don't want shelters near them because the homeless can be wild. For example, the night I arrived in Portland I started hearing a succession of booms. I got on to Reddit to find out that at the UHaul I'd dropped my trailer off at earlier that day that someone had tried to drill one of the gas tanks, which is made of magnesium, which sparked a fire. The fire spread to multiple vehicles and they exploded. Things like gunshots are heard pretty commonly; my neighbors deal meth, and down the street a man in the Mexican Mafia had a drive-by done on his house by his ex-girlfriend. PPB (Portland Police Bureau) isn't too interested in anything that's not immediately life threatening.
I didn't know these private security firms were doing this, and I'm glad they are now that I know. This situation between our county and city is what fuels this, though. PPB is its own beast; I haven't been here long enough to know what their issues are. In true Portland style, we are a bit miffed they had the energy to shutdown the Mushroom house downtown but not to deal with immense property crime. The problem with the model in this article is that stores are protected though not all businesses will pay for private security, so we have entire brands thinking about leaving Portland. People are left out of this equation though. If someone breaks into your house or your shed, I doubt you'll have the training to do what Echelon employees have. Oregon, over night, through Measure 114 also became the state with the strictest gun laws in the country thanks to Progressives and the Lutheran Church.
It's a wild state of affairs here past the Cascades.
