For those who missed it in previous threads...
No, you CANNOT "plaster someone's face and name all over the place to trigger people's memories".
There's a REASON police and media don't do it.
Because you'd essentially be saying, "this person is guilty" before they've been charged or gone to court.
Not only is it unfair but
it severely jeopardises any future criminal charges and trials.
Everyone (including you) has the right to defend themselves in a fair, unbiased and transparent court of law.
If your face and name are prematurely outed in relation to a crime, you can argue to have the case and charges dropped due to it being biased, and no-one will ever see justice for that particular crime.

very carefully. It's deliberate.
There are other ways to increase public awareness of a case, such as holding an inquest with witnesses, and releasing a reward for information
