Security experts are sending mixed messages about a new federal warning for airport safety.
The warning urges airport security personnel to be aware of ordinary items that look like improvised explosive device components, saying terrorists may be practicing to bomb planes.
Security expert Charles Slepian says aviation remains a top target of terrorism. The founder of Foreseeable Risk Analysis Center says the Transportation Security Administration doesn't get the seriousness of the message.
Slepian says some equipment that is relied upon can't distinguish between a block of explosives and certain cheeses and chocolate bars.
In contrast, another security expert says this is a routine type of situation that happens all the time. C-E-O of Investigative Management Group, Bob Strang, says there's no need to "be alarmed."
Strang says the warning shows T-S-A is doing its job by issuing the precautionary memo.
