You know who has trouble with "bad cops?" The people who don't respect authority in the first place. The people who have done things that harm others and the society at large. My daughter will never be in a confrontation with the authorities - never become a Michael Brown - because she has been raised to understand the need for the police and for keeping the peace (as much as I can teach her).
Your daughter will be in confrontation with authorities if, say, her house gets SWATed on a false charge (because an unreliable informant pointed at it), or simply because they got the wrong address or the wrong door. She won't get a chance to say "yes sir, please and thank you", because she won't be asked - the first thing she'll know is when her door is blown off the hinges with a shotgun and a flashbang comes in. Maybe it lands into her baby's crib, too. Maybe she gets a limb or two broken when they put her face down into the floow. Best case, they will only shoot the dogs and mess up the room with the entrance before they figure out something's wrong and leave (with no apologies and no compensation for damages).
Or perhaps she'll be driving around with a couple thousand dollars in cash, that she won in a lottery, and gets stopped by cops because they'll claim she's speeding (but really because she's cute). And when they see the money they will claim that such a large amount in cash is suspicious, and arrest it as proceeds from drug sales, because they get to pocket a good part of it for their PD (i.e. to buy more toys like MRAPs and .50 BMG sniper rifles for themselves).
If she is black, it might get even more interesting. For example, during a routine traffic stop (for which she needn't do anything wrong, they might just be randomly pulling people over) an officer will ask her for ID, and she'll reach for her pocket because that's where the wallet is... and get shot point blank because the officer thought she's reaching for the gun. Because that's what he thinks of first when he sees a black person reach for their waist.
Or maybe she'll get arrested on an outright false charge just because she happens to come across a cop who "just hates niggers, that is all".
FYI, all of the above is not a figment of my imagination. It's all real stories that happened right here in USA with different people. The chances of something like that affecting your daughter are still orders of magnitude higher than the chances of being killed by a terrorist. So rather promoting more surveillance state, you might want to talk to your representative in Congress about police militarization first.
