because of the past calls about them and having been there more than once just because some one said they heard automatic gun fire does not give them the right to go onto the property and search them. i can tell you as a master licensed peace officer being an instructor and already having my criminal justice degree that they most certainly cant just keep going onto this property to search them without a warrant and they know they shoot there so their is no probable cause for them to be there unless they actually hear what they think is automatic gun fire. as for exigent circumstance now that they are aware that these people shoot there mere gun fire wether automatic or not is not exigent circumstance, for them to enter the property and search them, hence the fourth amendment we still have to follow the rules of law, thats why we for now are still a free country, god hope we stay that way.
