insufficient evidence? few yrs back, I caught my neighbour
flashing (only saw his butt coz he ran too fast). 
i went home.. told my mom & we called the police.
We noe about dis pervert coz my maid kena many times too.
When the cops came, we went up to his place..bang on his door for
so long.. he don't dare to open. Until his wife came out.. let us
in.. they ask mi to point the pervert out. I said im not sure how
he looks like coz i only saw his butt! Then they ask my maid to
point. Meanwhile another neighbour heard the commotion.. joined in.
Called his daughter down.. told the police.. dat she also kena b4!
She too pointed him out. In the end.. he was jailed for
3mths.
Conclusion: with enough witnesses/victims.. no need to catch him
red-handed.. u can still nail him! work with ur neighbours.
