Uh oh! Better call the police and have the child taken away instead of talking directly to the parents...
But to put the danger in perspective, .09% of children (12 a year) died from electrical sockets out of all accidental deaths, compared to INTENTIONAL HOMOCIDE OF 11% (stats from cdc.org).
Theres no data if these electrical deaths were in the childs own home or elsewhere.
I like to think the people complaining to the authorities are also the ones who hate cops, because hipocracy is funny to me,
