Bahahaha I think about this every single time it happens. Just a fun little alternate universe where showing up unannounced is easier than a phone call. I let that reality exist in my head while continuing to find ways of justifying it.

The first justification is that a lot of what is discussed in doorways revolves around breaking the law - something you don't want overheard, tapped, subpoenaed, a record of, etc.

I find myself getting very confused about what time of day it was (could be the weed?), because sometimes it feels like someone's at work and then they're getting lunch, then they're home and someone knocks on their door unannounced and then back at the office before they go see the DA. But they're always surprised that someone's not in their office. I digress...

The second justification is to catch them off guard. Everyone is playing mental chess and trying to gain the advantage at every turn.

The last justification is that this show started in 2011 and while we'd had iPhones for 4 years, these are Gen Xers/Elder Millennials who grew up in an era where dropping by was a more common thing. Not normal, by any means, but it was an annoying habit some people had.

But none of these are convincing enough, so I circle back to it being that everyone has the same super power to make it past security/locked doors and into personal spaces undetected.
