If it were me, I'd be more cautious and use code words when out in public, though we won't know what they are without insider information unfortunately.

{ there's underground or outsider the city for secret meetings. many options are available to them. }

Hmm, it would be too risky to do that at this stage. If they were to do something rash, it would be difficult to ensure no one from the general public get hurt, even if we had the police stationed undercover at the venue. No, we should keep quiet about this for now and see how things proceed.
