Does business insurance cover rioting and looting?

Reports say at least 75 businesses were damaged when recent peaceful protests turned ugly in downtown Madison. That has many folks asking - does business insurance cover rioting and looting? 

Madison College Risk Management and Insurance instructor Martha Lester has been busy answering those questions for Channel 3, Channel 15 and
In Business Magazine. She's also doing a live interview with WIBA Radio. 

Lester says in most cases businesses are covered for damage - as long as they have a standard insurance policy.
