Burn Notice2007

Michael Westen:
[narrative] Suits of armor fell out of fashion because the added protection isn't worth the trade-off in speed and agility. Flak jackets and bulletproof vests are popular because they allow for a free range of motion. The key is to shield your core and mentally prepare for strikes against your unprotected arms and legs. All lightweight armor is vulnerable to some extent. Layered book cardboard won't stop a bullet, but it's dense enough to thwart all but the sharpest blade.
