BROOKLYN - The NYPD beefed up security at three Brooklyn schools in response to shooting threats made on social media. 

Police increased their presence at Edward R. Murrow, James Madison and Midwood high schools after they say threatening messages were posted online. 

Some parents say they thought twice about sending their children to school after being informed of the situation, but trusted that authorities have it under control. 

A spokesperson for the Department of Education says they're aware of the situation and are working with the NYPD to keep everyone safe.
