Jail almost by definition means pretrial detention, so "jailed without trial" is a tautology.

Nitpicking about the precise legal terminology is a bit pointless in this context.
If some protester got arrested for protesting, the reasonable thing to do is to call it just that, not "protester jailed without trial for protesting".
> A jail holds people for shorter periods of time (for example, less than a year) or for pre-trial detention and is usually operated by a local government, typically the county sheriff.
> A prison or penitentiary holds people for longer periods of time, such as many years, and is operated by a state or federal government. After a conviction, a sentenced person is sent to prison.
Here's an example of it used that way in Virginia's laws, at https://law.lis.virginia.gov/vacode/title18.2/chapter1/secti...
> The authorized punishments for conviction of a misdemeanor are:
> (a) For Class 1 misdemeanors, confinement in jail for not more than twelve months and a fine of not more than $2,500, either or both.
