I don't know if calling the flop is dangerous, exactly -- you won't be able to drive out a flush draw and probably won't be able to get rid of a gutshot, either. But I'd probably go ahead and raise, for value.

The limpers will most likely stay in with an ace, the case ten, or a draw, in a pot this big. Plus, if CO has AK, he may 3-bet.

In any event, after you called the flop, I think you should have at least raised on the turn. If CO's (or someone else) has trips, you should get some action.
