I'm not so sure about that. The one in the FBI sheet has an overall triangular shape, but its really a blue spiral. There are such spirals that are circular on other things that are almost certainly intended to be that particular orientation advertisement.
Regardless, the FBI sheet which everyone loves to quote is not "the law" on exactly how they are supposed to be. There is almost certainly slight variation. Its not like its a copy/paste symbol.
Having said that, the reason those symbols were chosen was because they are common symbols. It allows them to hide in plain sight. Seeing the symbol is not necessarily nefarious, but it is always at least somewhat suspicious.
