Karma demands the following.
Terrorists will attack an NBA playoff or all-star game in the next year. Several players will suffer grievous injury at best.
Which ones will be hurt? The ones who are staying home from this year's Olympics because of "security concerns".
It's their off season, which grows ever shorter. It's a chance to get injured, which is a very real concern. And although it's really hard to beat the prestige of an Olympic medal, they're not compensated for playing to my knowledge. And Kobe Bryant has some legal troubles to deal with. So it's not as if there's no understandable reason why an athlete might beg off.
But really now - do they think the security in Athens is worse than what they'd have on average at NBA games here in the US?
