This is the answer - burner laptop and phone you can lose without repercussions.

From my extensive research reading spy novels this would be something they do entering a high risk environment. If you absolutely have to have the data onsite at client meetings and don't want to use the cloud, then separate the data from the laptop. Maybe go old school with a USB stick. Make the USB stick look like a charger. Or pack a bag of 100 USB sticks with your company logo on them as chatchkes but one of them has the data.

I have to imagine if they are going to seize a laptop they probably aren't going to let you in anyhow.
