I don't think this is a fair or universal generalization.
Snowden ran. Leary ran. Rushdie ran. The Dalai Lama ran. Sometimes innocent people run.
Snowden ran after charges were filed against him. He admits to his actions. If he had stayed, he could have beaten the charges in court, because it is a defense to prosecution for a lesser crime to be committed (improper process of whistleblowing) to prevent a worse crime (various). But while Snowden is not innocent of the crime, he's simply got a valid defense to negate a guilty finding.
Rushdie fled a fatwa issued by a religious cleric, not the government, following the publication of The Satanic Verses. He was not charged with a crime by the government, but numerous individuals attempted to assassinate him for what they viewed as blasphemy of their religion.
The Dalai Lama, the then-legitimate ruler of Nepal, fled the Chinese occupiers of his country and set up a government-in-exile. He has never been charged with a crime by China.
Timothy Leary actually did commit a number of drug-related crimes including distribution, and ran because he was quite guilty. He also got caught a number of times and saw the inside of a number of jails and prisons...
Tibet
“He had not been charged when he went to Taiwan, so he is not considered to have fled the country“ [1].
Based on the original story, there should be plenty of evidence forthcoming. No need to jump to conclusions.

Anyway, he might be accused of sexual assault but he actually did nothing immoral. He just visited a legal site and had consensual sex with someone who claimed to be an adult at the time, and is in fact an adult now.

Innocent people don't run. Especially not before they've even seen what the evidence against them is.
