but you know the thing is if they feel you are suspicious they will investigate. If you are looking to be an explosive expert and they investigate you looking up explosives and you explain your instrest in being an explosive expert than they will see you as no threat. And about the being put in jail for thinking comment- the thing is if someone is thinking about something to that magnitude then it needs to be out to an end, if you stop something before it even starts then it ensures more safety for citizens. I feel that everyone is thinking that every person is monitored when in fact its people that draw attention to themselves and pose a threat to the security of the country.
