Unfortunately, neither of your statements is entirely true.

There are many cases where law enforcement and the legal system fail victims in a variety of ways (e.g., blaming the victim, improper handling of rape kits, police themselves might be predators looking for victims to target, etc). To put ones faith and protection entirely in the hands of 'the authorities' would be a dogmatic insistence on a single point of failure.

And an awareness campaign (or "tweets" and a "smear site" as you put it) can have merit. Consider predators such as Bill Cosby or Jerry Sandusky, who were powerful and had enough gravitas to cover up their crimes for decades. It was only when there was a public awareness campaign that numerous witnesses and victims had enough courage to come forward and actual charges could be filed.
