Parents are rightly concerned about the wave of cell phone robberies. Another was reported Tuesday when a 16-year-old was accosted at the Lawrence West station and intimidated into giving up his phone. Very recently two teens were robbed of a cell phone on Bessborough Drive. What to do. Of course, if threatened, the victim should give over the phone. Don’t risk harm. But many young people are careless about using their phone in a way that makes them targets. Don’t flash the phone around. Parents should make sure that records are kept of all phones and that a report is made to the police immediately. That should help to limit your liability. Finally, try to encourage kids not to put too much personal information in the phone. We all know that it can be used to defraud and impersonate .
