The American Children Anti-Stalking Law

We need a Federal law against adult strangers stalking a child under 18 years of age.
There is no law against an armed stranger following a child home. In the Trayvon Martin case the defense attorney pointed out it is not illegal for an adult stranger to follow, or in that case chase a child.
Only adult people the child is familiar with—parents, law enforcement, teachers, relatives, and people with official business or parental permission—should be able to legally pursue a child.
1. If a stranger frightens a child to the point that they run away or hide, the stranger should have to retreat.
2. A stranger with a concealed weapon should never be able to follow a child
3. A strange that follows a child and the child attempts to defend themselves, the stranger cannot plead self-defense
