Former and current judges, prosecutors and law enforcement are among those praising a bill coursing through the Legislature that reached a new level of urgency this summer after the July shooting attack on U.S. District Judge Esther Salas’ family by a gunman who tracked down her home address online.

While they contend the bill is a “good first step” in providing a critical layer of protection, many say enforcing it in the internet and social media age, where personal information can easily appear online, will undoubtedly be challenging.
