the situation in order for everybody to go home safe. if you think you can take me, one of us is going home hurt. i have my moral authority and physical authority. i should use my moral authority when i can. you re going to call me a racist, what kind of moral authority do i have? none. if anything gets a little bit out of control, i have only one authority, my physical authority. if you don t have legitimacy within the community as a law officer you re going to get backlash not people wanting to follow the law. my own fear that you re going to call me out on my legitimacy can sometimes ironically raise the level that s interesting, and very well put. congratulations on the launch and we ll keep our eye on it. thanks for being here. up next, a very different kind of science, could who you love be determined by what s inside? much more cycle ahead. m has afi, atrial fibrillation
