It is not the right thing to remain silent about illegal activities in the neighborhood, even if it is for the safety of your family. The reasons are as follows： First of all, if illegal activities are not stopped, they will continue to pose a threat to social order and public safety, and may cause more serious consequences. In the long run, it will not be conducive to the stability of the community environment where the family lives. Secondly, silence may make violators more unscrupulous, not only may they harm other neighbors, but they may also endanger themselves and their families due to the escalation of illegal activities in the future. Moreover, it is the responsibility and obligation of citizens to report illegal activities to relevant departments. You can use reasonable, safe and appropriate methods, such as anonymous reporting to the police or relevant law enforcement agencies, so that you can not only fulfill your responsibilities, but also protect your own safety to a certain extent. If you are worried about the safety of your family, you can try your best to protect your own and family members' information during the reporting process, and pay attention to neighborhood dynamics in the follow-up to ensure that measures are taken to maintain family safety. In short, you should not choose to be silent, but should properly deal with it in accordance with the law and regulations.
