Paintballs or pepperspray?

I was bcc'd into this email last night, from a friend who is well-versed in the dubious delights of military and 'security' technologies to Jon Snow of Channel 4 news. They raise this point about the bizarre-sounding Israeli claims that some of their commandos were armed with 'paintball guns' (presumably not those who were armed with live ammo):

Hi Jon
I've just watched your interview with an Israeli spokesman (who didn't believe your assertion that Turkey was considering sending a warship to protect a further aid boat wishing to dock in Gaza).
Can I suggest that you investigate whether those paint guns much mentioned in the piece were actually going to be firing pepper spray? I'm told that these weapons are used by Israel, sold to them by the US. This would of course also explain why the Israelis were wearing what look like gas masks rather than some form of goggles to protect them from paint spatter.
For example see www.pepperball.com (you may not see the exact model here, but you will see what is on the market).
Best wishes

The deeply unpleasant military-spec page on pepperball.com is here. The 'law enforcement and corrections' page has some stuff that looks even more like paintball toys.
Which would perhaps also account for the 'strange-smelling gas' that some of the passengers on the attacked boats reported?
