In the stock market, if you use inside information to procure an advantage in share dealing, you are breaking securities law.
If you front-run a clients orders you are breaking securities law.
If you commit a crime such as racketeering (extortion, loan-"sharking", bribery, and obstruction of justice in furtherance of illegal business) you are breaking securities law.
The recent headlines about the US and the UK obtaining inside information by "spying" on the private discussions about the trading of goods and services by their trading partners, breaches securities laws for insider trading, front running and racketeering.
This "spying" jeapordizes the interests of US companies in international trade and hence the interests of the US economy.
Who is going to prosecute the US actors for indulging in this activity that would be against securities laws? Who monitors the "spies" when they are not accountable for their actions in damaging the interests of the US?
