Why does the left tolerate crime and stand against imprisoning/institutionalizing homeless people?

I live in a province of Canada with a very progressive far left government (NDP). This province has laws that make it virtually impossible for cops to arrest criminals who commit theft under $5,000. Violent criminals and drug addicts are left to roam around the streets and the public freely and do their drugs in broad daylight. If you go to any childrens playground in my city there will be a group of homeless people passed out on a bench from fentanyl. There have been multiple cases of kids stepping on glass pipes or needles in parks or beaches.

I have witnessed on multiple occasions homeless people just walking into stores and taking whatever they want and walking out WITH POLICE RIGHT OUTSIDE. buisnesses are closing and prices are skyrocketing as buisnesses try to maintain their profits despite losing massive amounts of money to theft. Security companies are not allowed to touch these criminals or else they will be charged. Self defence is practically forbidden in any form.

To me this level of delusional empathy is doing nobody any good. How is it even remotley controversial that criminals should be arrested and locked away?
