Let me 'splain to you a scenario I encountered recently.
A young man turned in his cousin who had several warrants out for his arrest. Because the young man had a job and a fairly predictable schedule, bounty hunters routinely 'hung around' to see if said cousin would show up. Growing tired of being trailed he finally turned his cousin in when he had shown up at the young man's place of business.
The mom of the cousin (the young man's aunt) became enraged as did the cousin's sister (yet another cousin) and expressed their disgust at the young man in their best Jerry Springer Show vernacular.
The next day a calling card from Child Protective Services (CPS) appears on their door. They had come to inspect the home of the young man who lives with his wife and 1 year old daughter. Apparently an anonymous call to CPS initiated the need for an inspector to look for signs of abuse. They called CPS back and told them to come to the house the next possible day.
During that evening the couple called around to find out who would've done this. After only a little investigation it seems all evidence points back to the Aunt and the Sister Cousin. There was word also that the aunt and the cousin intended to have more people (their friends) call anonymously to CPS.
When CPS did their inspection they found the same things I've found whenever I personally have visited their home. A well-fed, cared for, happy, and loved 1 year old girl. The young man and his wife explained what had transpired over the week and explained that more 'anonymous' tips were likely to come.
The CPS inspector said if more tips came in (whether they were false or not) they would have to follow-up on them and eventually demand that the young man and his wife take a drug test. Hearing this the young man and his wife asked where they could take a drug test that very day to get it cleared up. They had the test taken but the problem was still up-in-the-air because follow-up would be necessary if more reports came in.
"Can't something be done about them making false reports?" The young man asked. The CPS inspector explained that they do not require those who make anonymous reports to be accountable so that people are not discouraged from calling if they suspect abuse.
What will happen to the young man and his wife? Maybe something, maybe nothing. But because they are attempting to comply with the law they have become the soft targets of law enforcement. CPS will return to their home and pile up a big long record on them only because they are cooperating with the law.
Wouldn't it be nice if law enforcement focused on the initiation of force, theft AND fraud?
