In response to Donna Maiden's letter about the so-called "junk vehicles" on her farm property, she actually can find out who the self-righteous tattletale is. All she has to do is file under the Freedom of Information Act. The name of the unknown person in question will be released and brought into the light. Absolutely true. Works every time.
Perhaps the busybodies' time could be better served working toward a solution in dealing wit your "up and growing" gang problem, like invoking and enforcing curfews. Fine the parents of children who don't comply. Make gang association a felony with mandatory jail time. Use RICO Act. Get tough!
