Comparative criminal justice

Present state of electronic technology makes it possible for state authorities to control citizens' activity in every moment oh his/her life. On the other hand none of us want to be controlled this way and democratic rights shall guarantee our privacy to be preserved. Yet proactive police techniques can be useful in protecting us against those of our co – citizens who do not respect the legal order. The criminal investigation nowadays cannot exist without using proactive techniques – no matter if it takes place in Poland or USA. Thus the problem emerges how to choose when these techniques should be used and who should make this decision. The key-guarantee of respecting human rights in this case is external control of police activities. Proactive techniques are usually kept secret; therefore control seems to be impossible. Disclosure in criminal trial is the necessary condition for preventing abuses. Post fact revealing of all the actions taken by the Police is the best way to ensure legality. Both Polish and American legal systems try to balance the right to a fair trial and efficiency of an investigation. Surveillance, infiltration and police "provocation" are used in both countries but the legal solutions are quite different; especially considering checks and balances. It seems that polish legislator intentionally omitted most strict limitations as they cause problems for state authorities. Police lobby must have been much more effective than "human rights" lobby. Analyzing the level of protection of the citizen during criminal trial, it must be noticed that current American solutions are much more appropriate.
