It is only a matter of time that Jane Fonda (81) ends up in jail with her weekly climate protest. She has been arrested four times and by a fifth time she may have to “hum” for a while, TMZ reports.

The American actress, who is now mainly a political activist, protested for the seventh time in a row at the Capitol in Washington on Friday. To prevent arrest, she looked it up when agents wanted to intervene. She quickly left for the balcony, where she thought she was safe enough.

Justice in Washington says that the actress will not be charged for the four times she has been arrested, but notes that a fifth arrest could result in a large prison sentence. Jane Fonda is the face of the climate protesters in Washington.
