Most JWs don't see this as a problem. They reason that. just like the JWs, the police will not convict a pedophile over the story of one victim alone, there must be collaborative evidence.
Instead, the message (in the media or protest posters) should be "Collaborate with the police" or "Why don't you work with the police?".
They fail to understand that JWs are actually a problem in the investigative process.
1) They do not advise or offer help to their members to go to the police.
2) They do not help police investigation, non what's so ever. Went as far as to advise elders not to take notes and not to keep them at home; even destroy them.
3) They do not urge their members to collaborate with police investigation.
4) They have never stated that evidence gathered by police could be considered a second witness.
Due to the above, they unwillingly shield the pedophiles from justice.
Unfortunately, though the documentary on W5 will be highly effective with non-JWs, I fear that most of the JWs will look away as soon as criticism to the 2 witness rule is brought up.
