This is quite troubling.

Prompt Injection Via Road Signs

Abstract: Embodied Artificial Intelligence (AI) promises to handle edge cases in robotic vehicle systems where data is scarce by using common-sense reasoning grounded in perception and action to generalize beyond training distributions and adapt to novel real-world situations. These capabilities, however, also create new security risks. In this paper, we introduce CHAI (Command Hijacking against embodied AI), a new class of prompt-based attacks that exploit the multimodal language interpretation abilities of Large Visual-Language Models (LVLMs). CHAI embeds deceptive natural language instructions, such as misleading signs, in visual input, systematically searches the token space, builds a dictionary of prompts, and guides an attacker model to generate Visual Attack Prompts. We evaluate CHAI on four LVLM agents; drone emergency landing, autonomous driving, and aerial object tracking, and on a real robotic vehicle. Our experiments show that CHAI consistently outperforms state-of-the-art attacks. By exploiting the semantic and multimodal reasoning strengths of next-generation embodied AI systems, CHAI underscores the urgent need for defenses that extend beyond traditional adversarial robustness.

How Many Guns in the U.S.:

Report Highlights: The United States has more civilian-owned guns than any other nation. Estimates suggest the country has hundreds of millions of firearms.

The United States has between 400 million and 500 million privately owned firearms.

46% of American households, approximately 65.19 million, contain at least one firearm.

In 2026, there are 1.5 guns per U.S. resident, and 2 guns per U.S. adult (over 18).

The majority of firearms in the U.S. are handguns (55-60%).

ICE Expansion and the Architecture of a Security State

The militarization of American cities by ICE is being addressed, or not addressed, around constitutional, moral, and practical questions familiar to Americans from sixty years of debates over “law and order.” Does ICE’s deployment follow the law? What kind of deference is law enforcement due? Is the force deployed by ICE proportional to the threat? And, in general, is it appropriate to oppose the fact that a duly-elected president who was put into office on a promise of deporting illegal immigrants is actually fulfilling that promise? All of these are worthy questions on which reasonable people can disagree. But they are not the most relevant questions, and their relative irrelevance is why they have been embraced so enthusiastically by both political parties and their corporate media outlets. These questions keep the conversation on safely ahistoric ground, distracting from the question of what ICE’s expansion represents structurally. Namely, the accelerating growth of unconstitutional arrangements, institutions, laws, and precedents that create our Founders’ ultimate fear: a domestic military force and its concomitant institutional supports...
