Can you legally picket a major retailer?

Yes, you can legally picket a major retailer, as long as you adhere to local laws and regulations regarding protests and demonstrations. You must typically ensure that your actions do not block entrances, disrupt business operations, or violate any ordinances related to noise or public assembly. Additionally, it's important to respect private property rights, as picketing on the retailer's property may require permission. Always check local laws and guidelines to ensure compliance.
