Here's a couple or current examples from ABC News stating it exactly that way:
"A Florida man was arrested Wednesday for allegedly hacking into the emails of Scarlett Johansson, Mila Kunis and other high-wattage stars and leaking private photos of the women to Internet sites. "
Or how about these:
A 43-year-old Morristown man has been arrested for allegedly molesting a 10-year-old girl after offering to help her after she fell off her scooter.
Per the above, no they don't
Can be ture is not the same as is true. What exactly is your problem with giving someone the benefit of the doubt until they are actually conviced?
As someone pointed out, how would you like it if they arrested you at a playground, mistaking you for the child molester and the paper ran the story:
Homeguy was arrested today for molesting a child on the local school grounds before you had a trial? Maybe you wouldn't care. But all the news organizations obviously do, so they insert the allegedly to be fair and help avoid a lawsuit.
