A 'Welfare Check' 

When people of higher authority in certain small townships (normally more cases north of the mason Dixon line and worse large cities in common wealth states such as Pennsylvania or surrounding states such as New York)

Corrupted law enforcement (one bad apple of the group in any Police department) will stop by your house, if it's unlocked or seems unlocked, they will perform a 'welfare check' which is just a way to enter a home illegally, steal, plant evidence etc. Just a loop hole to invade somelone house based purely on unethical servants of the community.
