The police are out there arresting the drunk drivers or the shop lifters and don't have time for your cat stuck in a tree or the neighbors fist fighting in their front yard. They are on their property and there is no deadly weapon present.
In addition to donating your time and resources to charity organizations, you can also fill your need to help your fellow humankind by donating money to total strangers in their time of need on GoFundMe.com.
