Because of actual laws concerning it is actually illegal to beg for money from people on the street, it is illegal to shoplift and steal from store owners, and it is actually considered a "private property" and their own security has the right to remove whomever they choose from "private property". Most shopping malls have posted somewhere on their property on the parking lot that it is, indeed "private property" and they have the right to remove anyone from the property at any time. It is not that homeless people are not people, but unfortunately some people really want to shop without someone coming up and accosting them or begging for money. Whenever I go grocery shopping in town, I have to really be prepared for homeless people in the supermarket parking lots and at the gas station begging for money I don't have. I have already been attacked by a person asking for money at a gas station and I do not want to be attacked again, so now I shop at places where security has the right to remove people from the premises and shop safely. Businesses who address homeless people sleeping in front of their stores do so for the safety of their customers. Homeless people still have contagious diseases, have been known to rob people in the parking lot at knife point, have been known to destroy or vandalize the property, and have been known to just plain scare people away from the business and people no longer spend money at the business. Yes, we should have in our hearts to care for those who have no homes, but being "homeless" and bringing out "homeless awareness" and being kind to the "homeless" has not changed the truth that most are addicted to drugs and will beat up and steal money from a victim to buy more drugs. So because of actual laws regarding private property and the right to refuse service to anyone, most shopping malls are allowed to have security keep the homeless from hanging out at shopping malls to prevent scaring away customers, to prevent vandalism, to prevent poor sanitation issues from homeless people not using toilets or using facilities properly (they tend to leave water faucets on and running, they urinate not in toilet facilities, and they tend to leave trash on the ground instead of using trash receptacles -- and I have personally witnessed this again and again.) So the shopping malls are exercising their rights to remove some people to make it a safe place to shop for other people. It seems harsh, but, well, prevention is still the key to avoiding worse problems.
