How can I know SEC is ensuring it doesn't happen?

since it was stated here that "holding" was illegal
& most agree that use of ramping, wash sales,
manipulation of price and liquidity are also illegal,
I get the impression that this is frequently
done in the course of high frequency trading,
How do I know this isn't happening, and how
can I know SEC is ensuring it doesn't happen?
