 Gangs use the Internet to communicate with each other, facilitate criminal activity, spread their message and culture around the nation.As Internet pages like YouTube, Twitter and Facebook become more popular, law enforcement works to understand how to conduct investigations related to gang activity in an online environment.In most cases the police can and will get the information they need, however this requires police officers and federal agents to make formal legal requests for information in a timely manner, which typically requires a search warrant or subpoena to compel the service providers to supply the needed information.
