Stephanie Meyer tried to answer this question on her website, explaining that unlike the other vampires powers, Jasper's power is actually affecting Bella physically by adjusting her pulse and endorphins to calm her down.
Vampires were killed all the time by other vampires and the werewolves. But accepting all this, the question is: Why could Jasper change Bella's emotions?
Why didn't Edward just pick a fight with the Quileute tribe by breaking their treaty instead of traveling all the way to Volterra, Italy to "expose" himself as a vampire in front of the Volturi? After all, wouldn't manipulating her emotions technically be messing with her mind?
Which is what a depressed Edward does in universe, most people believed the standard widely-held vampire myths. That's why Edward and Aro couldn't read her mind, Jane couldn't make her feel pain (it was only creating the illusion of pain), and Zafrina couldn't make her see visual projections she was able to make everyone else see.
So as far as anyone who wasn't a vampire was concerned, a vampire getting hit by sunlight would burst into flames, not sparkle like a glittery disco ball. And why did Edward have to travel all the way to Volterra to reveal himself anyway?! Alice could to see her future, though, because Bella's future happens outside the mind.
