Does this checkpoint mean that Border Patrol agents will be doing sweeps through Friday Harbor or any other community?
The Border Patrol mission is focused on security at and near the border. Checkpoint operations support that mission. Roving patrols of urban areas, worksite enforcement and identification or apprehension of domiciled aliens are not part of that mission – those activities are the province of Immigration and Customs Enforcement (ICE). Thus, checkpoints are exactly that and nothing more.
