Cellphone data: Lockdown protests may have spread virus widely

One visualization shows that in Lansing, Michigan, after a 30 April protest in which armed protesters stormed the capitol building and state police were forced to physically block access to Governor Gretchen Whitmer, devices which had been present at the protest site can be seen returning to all parts of the state, from Detroit to remote towns in the state’s north.

One device visible in the data traveled to and from Afton, which is over 180 miles from the capital. Others reached, and some crossed, the Indiana border.

In the 48 hours following a 19 April “Operation Gridlock” protest in Denver, devices reached the borders of neighboring states including Wyoming, Nebraska, Oklahoma, New Mexico and Utah.
