Why on earth wouldn't you want toilets for the homeless to have enough privacy for a drug deal? The alternative is having the drug deals done in public where I and my kids have to see it happen.
What's wrong with exchanging money and goods that you need to shield your children from? What about the events that happen after, injections of said goods?
Yes, you're right, which is why when I lived in the city I lived away from neighborhoods where that kind of stuff happened, when that activity came to my neighborhood I moved out of the city. The city didn't seem to want to move the drug dealers and users, so I had to move myself.
