while there may be some reasons to be concerned with this bill, please do not jump to conclusions. first of all, no provision of this bill would go into effect unless a state of emergency has been declared. it is designed to deal with something like ebola or another viral outbreak.
as far as someone entering your property, they would need probable cause. this would be the same standard police are held to every day. for example, if someone owned a farm and a herd of livestock became ill with some horribly infectious disease, DPH officials could (if an emergency has been declared) enter their property to deal with the situation.
there is no provision in this bill to allow for the confiscation of your firearms, nor would your firearms fall under the authority of DPH during a declared emergency. to my knowledge there is nothing in this bill that has not already been upheld by the USSC (please correct me if i'm wrong). Also, contrary to popular belief, this bill also does not mandate swine flue vaccinations or any other vaccination.
this bill has been filed many times over the last few years and has not become law. also, the house recently debated this and made some changes to the language. I have been told that the house changed some of the "concerning" sections of the bill. I haven't actually seen those changes yet so i'm not sure what they did.
please dont get me wrong. i'm not trying to tell anyone what they should or should not be concerned about with this bill. it just seems like there is a lot of misinformation and conspiracy theories out there surrounding this one.
