Anyone who will commit a crime by break into a country will likely commit a crime to remain in the country. Breaking and entering does not require using force but only to enter without legal permission. That explains the distinction of people in the USA, i.e. citizens and illegal alien. Some are here legally and some are here illegally.
Who knows what someone else will do if they feel threatened or in danger? Its best to use good judgment and seek the advise of those who deal with law enforcement. Not the tourist board.
