now to the drama playing out in rural oregon tonight. the armed anti-government protesters who've taken over a group of federal buildings. police are keeping their distance for now, hoping to ride this thing out, but many critics are asking, would the cops be handling the sittion differently if the protesters were black ormuslim? abc's neal karlinsky is on the scene tonight. > reporte tonight a bizarre standoff in oregon. >> i am 100% willing to lay my fe down to fight against tyranny in this country. >> reporter: as several dozen militiamen, some openly armed, hold their ground at this federal wildlife refuge which they took over while no one was here. and we found the man who posted that vid inside. >> do you fear that this could turn into something serious enough that you would not be able to retururno your family? >> there's always that chance. nobody -- i'll tell you right

re that first shot. we will protect ourselves. but that's not what -- that's not what we want and i don't think that's what they want. >> reporter: the events at first glance might seem like the 2014 armed standoff between ranchers and federal agents in nevada. >> get back! get back now! >> reporter: but there's no violence or confrontation here in oregon. what there is is some of the same characters. in fact, members of the bundy family from nevada behind that standoff are at the center of this one as well. >> this refuge here is rightfully owned by the people. and we intend to use it. >> reporter: they is i they're fighting for nothing short of the liberation of thousands of square miles of federal land which they believe should be returned to america's ranchers. >> to say that this is all taking place in the middle of nowhere is an understatement. thnearest town is a solid 40-minute drive away.

they would deny it to your face, but that's a blatant lie. >> reporter: tonight public support wavering as the militia is skewered online. the hashtags y'allqaeda and vanilla isis picking up steam throughout the day. some complaining that the lack of law enforcement presence is a sign of a dououble standard. >> look, the fbi, they know what's going on. they know that you have these largely white militias and they're carrying heavy artillery. you cannot convince me that federal law enforcement would react the exact same way if you were dealing with some folks who were black lives matter activists. >> reporter: but the militiamen say their fight goes across color lines. >> god intended that his children be free, regardless of race, color, or creed. and i will stand with any man who will stand for freedom. >> reporter: the fbi saying only that they're investigating the actions of the militia. tonight the sheriff going a step further and urging them to go

si i see them on the flip side. >> reporter: lavoy comes from a long line of ranchers. >> this is happening throughout the west. i've met with rancher in utah. they'r're getti pressed and pushed from every side. >> reporter: police have been largely absent inn ts standoff. but lavoy has been in this spot before. joining rancher cliven bundy in that 2014 face-off wit federal agents over cattle grazing rights. >> get back! get back now! >> reporter: for 20 years rancher cliven bundy refused to pay rent to herd his cattle on government land, resulting in $1.1 million in grazing fees. >> so i have no contract with the united states government. >> back up! >> reporter: federal agents armed with tasers and dogs evicted his cows, seizing hundreds. anti-gernment groups and armed militia members joining the fight. the confrontation turning rough.
