I have been reading that this is a possibility, especially in the large liberal cities where they have been able to hide out better. This is one of the reasons that President Trump wanted to remove as many of the gangs as possible before he even did anything with either Venezuela or Iran.I'm hearing sleeper cells that came in under Biden policies appear to be activating.
All of the Somalis and other Islamic here have been saying that they support the Islamic regime in Iran , so it is possible that there can be some sleeper cells causing problems.
The warnings were to try and stay away from large groups of people, where they think attacks might happen, and i believe that law enforcement everywhere is on a sharp watch for anything like this .
It is defnintely good to be careful right now.
