Reply To: why is everyone arrested called a suspect?

@Participant
A reputable headline would read:
“Armed man arrested in killing of 12 year old girl.”
In means in response to the act of the girl being killed.
No libel can be ascribed to the headline you wrote because man is generic, if it actually used the arrestee’s name and the story did not use verbiage such as alleged it may be problematic.
Any libel action Would wait until after trial. If convicted there is no liability, as truth is always an acceptable defense to libel. There are others, and malicious intent may have to be proven in some jurisdictions. Here the intent appears to be to sell newspapers
