GW's Crime Tips Hotline, (202) 994-TIPS, allows individuals to leave a confidential voicemail message. (202) 994-TIPS allows people who have information -- but don't come forward because they don't want to go on the record -- a way to report incidents with the promise of strict confidentiality. It's important to remember that you should only use the TIPS line for non-emergencies. Call (202) 994-6111 for all emergencies. The TIPS line has been useful to individuals in the past who provided information about a specific incident or a repeating problem but wished to do so anonymously.
General guidelines when calling:
Give information about who, what, when, where, why, etc.
If your message is too long & you are cut off by the voicemail system, call back.
While it is not mandatory that callers leave a first name or return phone number, it aids in investigation.
