Picking "good targets" isn't an activity that exists in a vacuum. You need to:
Gather reliable intelligence on the enemy
Analyze their systems and networks
Identify key stakeholders
Analyze effects those stakeholders have
Project effects neutralizing stakeholders will have on systems and networks
Weigh different options and their cost/risk/benefits/plausability
Gather intelligence on stakeholder that will make intervention possible (residences, work places, schedules, security, and those of others in close proximity/relationships with stakeholder)
Plan and practice for intervention
Execute intervention in a manner that allows you to repeat
All of this requires cooperation and coordination denied to us by an artificially maintained leadership vacuum. Like I said though, and part of the Left's strategy, there are inherently no "good targets". No matter who the individual kills or what he destroys, another Leftist will slide in from the shadowy mass of their collective psychosis to fill the departed agent/s' space, another corporate think tank office. The latter is harder to replace however.
High value targets at this point are infrastructure networked Leftists have invested in, a good deal of their effort is locked in tangible assets and institutions that they use to mass produce their horizontally distributed power base. The game would be to destroy these consistently in a low cost and repeatable way.
