I would risk it and take in the ones you can, have them neutered and whatever else the vet finds they need. And call animal control.

I would hesitate to try to educate her for 2 reasons. 1. you have reason to believe they use crack. Trying to educate them may make them angry and you don't want someone on crack anygry with you! 2. people have to want to be educated. So far she is not interested.

Another thing to consider, rather than calling animal control. Is there a rescue group near you? Maybe one that works with ferals - (hey, we THOUGHT they were feral, they weren't fixed, wormed, fed, collared, etc.). Or some other program that works with strays. Then call those groups to see if they can help out at all. If they have foster homes available, great, the entire burden doesn't fall on you!

Good luck, let us know what develops!
